I think it is a valid concept. I just don't care what it is called.

Keep it, I agree with Jakob's points.

Just because someone doesn't understand it and someone thinks it is "subjective", that doesn't mean it should automatically go bye-bye. It just means we as a website, a community, and a staff should look at clarifying the term itself for the rest of the industry to go by rather than say "this idea is stupid, so let's kill it off".  If we all can't come up with a clarified term that can be widely accepted, THAT is when I'd agree with deleting the concept page.

QFT. The discussion is not about the various cultural context definitions of a word like "boot" or "geek". This is a matter of industry specific vocabulary that should not be subjective, it should be defined and supported by examples used by the industry, not just forum threads.  If 20 people out of 30 think hamburgers must contain ham, that doesn't make the ingredients subjective, that means those 20 people are uneducated about towns named Hamburg.

 Also, arguing "nearly all game are polygonal these days" does not hold up very well on a database of all video games in history.

Rename 2.5D to "Polygonal graphics on a 2-dimensional plane", alias: 2.5D.

Problem solved? Kinda.

Conceptually speaking, I think it still needs a definition. Take Abe HD for example. Or Duke Nukem: Manhatten Project, how would you define them?

There are 3D platformers, games that use polygonal graphics and a character that moves around in 3-dimensional space.
There are 2D platformers, which use sprites

... and characters rendered on a 2-dimensional plane, there is zero depth to the visuals.

So what of games that take the concept of a 3D platformer and apply them to a fixed 2D path? They are a genre of games that don't fit into either of those two concepts without concessions.

So why not refine the term rather than outright delete it? MK is a 3D fighting game on a 2D plane, but it is not singularly either 3D or 2D.

It is a concept! It exists, and there's no reason to delete it just because it's a mishandle-mash of graphics and gameplay. The term Concept is broad for a reason, in my opinion.

I never thought 2.5D really described a sidescroller with polygonal graphics.. That's still a 2D sidescroller (but with polygons)

My idea of 2.5D was always something like Klonoa  -- It has to be a sidescroller, but gives you some level of interaction with the background, thus the "half dimension" --->   You are walking sideways for the most part - but can occasionally take a step up or down.

(Some sidescrolling bits of Paper Mario also come to mind, but those games are mostly full-on 3D adventure RPG's.    Streets of Rage doesn't really qualify either - yes they're essentially "sidescrollers with depth" - but we classify those as "brawlers" or "beat-em ups" (not sure the distinction between those 2)

But this is a very interesting debate! And it definitely does seem to have multiple meanings to people at this point..

The term is often referenced (and has a very specific meaning in the context of videogames) and people will want to know what it means. Therefore the entry's existence in the wiki is justified - no matter whether it's stupid or not.

@Jeff I think the term was initially created for games like New Super Mario Brothers where 3D polygonal characters were pasted on 2D sprite backgrounds. It was 2.5D because there were both sprites and polygons in the same game. For a game that is made with polygons in a 2D plane, I would simply call it a side-scrolling game.

Reading the page I find it difficult to believe that it says the the term is used incorrectly to refer to games like Doom... SINCE THOSE GAMES USED THE TERM FIRST! (sorry, got carried away there)...

In my quick run thru the list of games I don't see any that used 3D models on a 2D background that predate Ultima Underword (which, BTW, should be on the page under this definition, and isn't)... That doesn't mean there aren't any, it just means that I don't recognize them off the top of my head as being games that arrived earlier.

Did 2.5D get retroactively applied to 3D space games with 2D sprites? No? Then the page needs to reflect the reality of the history of the term. The fact that no one is making those games NOW doesn't mean that the older use of the word is "incorrect" (kids these days, go on, forget history, see if I care).

Also, as pointed out above, if this is a term used commonly in gaming (particularly by game producers) we need to have it in the "most comprehensive game wiki" regardless of the "Yeeeeuuuccckkk" factor the term inspires.

um I do believe the term 2.5d was actually coined by some of the first developers that said instead of making a 3d open concept lets just make every thing 3d then limit it to a 2d plane...
so if the industry coined it it should be kept...

The first time I heard this term was in Nintendo Power when they were previewing Yoshi's Story. I think it was a way for marketeers to point out that while their game was 2D, but still had those cool 3D rendered characters which were so impressive at the time. Now that 3D graphics are in web browsers, its a flag with no wind. Regardless, I think the term is important historically. It will always have a place in my heart, since I reminds me of a lot of great titles in the early days of 3D rendered video games.

The term is ubiquitous in the gaming vernacular now (and frankly, has been for years), so you pretty much have to keep it. I know it doesn't make sense when you break it down literally, but the term is widely accepted as defining a particular game style (3D graphics on a 2D plane). It is what it is. *shrug*

@jakob187: I would like to propose that we only use "QFT" to mean "Quit Fucking Talking" from here on out. Way funnier, way more aggressive.

QFT.

Here's my contribution to this discussion:  
 
Quakertown Fried Turkey. Anyone up for a bucket of QFT?  
 
Yeah, think about it. 

 Stereoscopy could be applied to either, though why anyone would make Streets Of Rage using stereoscopy I have no idea...

Deleting it from GB won't make it go away :/ People will still use the term.

No dumbist term is  HD  and HD remake and Hd graphics  since everybody fucking thinks if they add HD to it, it means it fucking looks better even though the real reason it looks better is because they redid the game not up the resolution.
 
Example 1  serious sam HD
 
Oh look that game had it's 3d engine overhalled to serious engine 3  and texture redone even though it already fucking ran  at HD rresolution on the damn PC and beyond back in 2000 when it first fucking came out.,  
 
that is a  total fucking redo and recode of the games graphic engine a HD resolution has NOTHING to do with it looking better it ran in HD before.
 
Oh the list goes on Beyond good and evil HD prince of persia HD  that serious sam HD ETC ETC  they already was in fucking HD resolution that is not a HD remake .    and look we are going to upscale that  and call it a HD remake and console noobs will totaly buy into that it must be easy to sell old games these days since all they got to do is add HD onto and everybody will think it is the best thing since sliced bread.
 

 No you people want the  Old game graphics engine textures 3d models  totaly fucking redone  and running at a   1920×1080 or 1780×956   that wont do next to anything anyway and might even look worse since the lower res game art now has to fill that HD resolution.
  
You people sound like those fucking morons that are on those HD vision sunglasses TV infomercials when you talk up this crap like your HDTV is some fucking magic box  that makes all old games look better and it is untouched by unholy hands for all new games in mkaing them look good. .
  
it grinds on my ears when people going around doing this HD crap and they have no IDEA what the fuck HD even really means.
   
99.9% of that HD  terms crap  should stop being used  and i is been fucking 8 or 9 years since  non- rich people could buy HDTV and the first xbox ran up to 1080i Res in widescreen  give it up already/.;
  
 
I mean god  when mega man 9 and mega man 10 came out I herd Noobs going on how crappy it looked not in fucking "HD", well guess what you people playing on the damn xbox or ps3 it fucking runs at  720p and 1080p resolution.  (and 480i on wii like a real NES game)  
   
No you think mega man 9 looks like crap because it modeled after a 8-bit game nothing to do with HD or "HD graphics"slapping fucking No " HD graphics"  on a reason you think the game looks like crap won't help you just look like a technically ignorant dumb ass.
  

I am not wildly against 2.5d. I find it to be a reasonable distinction between a game like the most recent sprite based mega man games and splosion man. I think comic jumper is a good example of 2.5d.

We should lock the 2D page into having a link to both a 2D Gameplay and 2D Graphics concept page.

To me, the term only fits 2d games with some illusion of depth, like shooting into the background in Shadow Complex.

The hell? I know 2.5D as in oldschool sprite-based games in 3D worlds, like Wolfenstein 3-D, Doom, Duke3D, etc. Never heard it used when talking about an actual 3D game in which you only move in two dimensions. Using it THAT way sounds pretty silly to me.

When talking about side-scrolling platforms or fighting games that take place only on the X and Y axes, it's stupid to call them anything else than just 2D games, regardless of their graphics. "2D with 3D elements" is appropriate for games like LittleBigPlanet and Klonoa, but "2.5D" should be reserved for games that attempt to emulate a 3D environment with 2D art, such as Doom and Wolfenstein 3D.

Oh, and while I'm at it, "AAA" is stupid too. What's that mean? A shit-ton of money got spent making stupidly high resolution textures that only 3 people will notice anyway?
