I have too many games.

You can say I am a compulsive buyer. I fall for every Steam Holiday sale, midweek sale and weekend sale. As a result I have over 20 games on my PC which I haven't yet played. I'm typing this on a MAC, so I can't look at the painfully endless list right now (not sure if I want to), but I'll try to recall as many titles as possible and list them below along with some non-Steam games also for the PC:
 

• BioShock
• Braid
• Indigo Prophecy (that's its proper name, shut up)
• GTA IV
• The Chronicles of Riddick: Assault on Dark Athena (which includes Escape from Butcher Bay)
• Medieval II: Total War
• Psychonauts
• Borderlands
• Mass Effect (second playthrough)
• Mass Effect 2
• Half Life 2: Episode 2
• Trine
• Hitman: Blood Money
• Fallout 3
• Sins of a Solar Empire
• KOTOR
• Spore
• Freedom Force
• Freedom Force vs. the 3rd Reich
• The Secret of Monkey Island: Special Edition

If you haven't heard any spoilers for it, play through the original BioShock. Psychonauts is also a fun little game to play.

Sucks for you, sucka.
 
*goes to play a game*

I really enjoyed Trine. It's not particularly long, but I found both the puzzle solving and combat to be really, really satisfying. If got it while it was on sale for $5 like I did, you'll definitely get more than your money's worth out of it.

stop bitching and get to work son

Ditto, thanks to Steam my PC games collection has grown exponetially. My hard drive doesn't even has space left to install anything. But when I do buy I definitely do with the intention of eventually playing said games.  
 
Let me suggest you just pick one game, whether it be on PC or console and stick with it 'till the end (if it's single player). I say start with Half Life Ep. 2.

Show off....I just have 22 or something games.  >.>

I have alot more games than you on pc, steam and non steam, then again your using a mac. Yes I also fall for those sales, I guess I better get started then. I'm really enjoying splinter cell conviction, remember, you need a very powerful rig to run that game, or not use anti aliasing or less of it.  
 
Also i'm noticing i'm running out of hardrive space, I am in the process of uninstalling a third of my games to make room.

Geez, I have like 70 games I haven't played yet...

I'm gonna suggest Braid first since it should take the least amount of time to finish. It's also a truly amazing game every gamer should try out. 
 
After that... I don't know. I'd have the same problem deciding myself. In fact, I actually have the same problem. Damn Steam and their low, low prices.

Play Indigo Prophecy. That is a truly incredible experience in gaming. It's like, an earlier version of Heavy Rain and you can see the design shining through, with an awesome story to boot!

Ouch. I know the feeling, Snail. Believe me, I do. 
 
Having recently played it myself, I'm going to recommend The Secret of Monkey Island: Special Edition. That game's got charm coming out of its giant monkey ears, is still incredibly funny, and the updated interface, graphics, music and voice acting make it feel like a truly contemporary experience. That being said, it is kinda taxing on the old grey matter in points, but I think it's well worth your time to check out if you like games that make you laugh and/or encourage you to think.

Yes. You DO want The Chronicles of Riddick that game is fucking fantastic. 

I have 40 GBA games alone. I have like 50 console games.

These 2, or Braid. Braid is relatively short so you can knock it out quick. "

• Assassin's Creed 2
• Gears of War 2 GOTY Edition
• Tekken 5
• Killer 7
• KOF 98: Ultimate Match
• Marvel vs Capcom 2
• Soul Calibur
• Shadow Complex

I feel your pain. It wasn't until maybe 3-4 years ago that for some reason I started collecting and buying more games than I have time to play. It's a curse, but if you're a cheap-ass like it's not too bad. I rarely buy a game for more than 10 euro.

Screw all the other games, and go play Psychonauts!

In case it wasn't mentioned before, you can check your steam list anywhere by going to steampowered.com and logging into your account.

I'm the same: not as many, but still got a lot.

You can neverhave enough games.

There must be 3 or 4 hundred games I own that I havn't finished. At least. Oops.

The only real answer to your problem is to stock up on a few weeks worth of food and water, lock your doors, turn off/unplug your phones, turn off the lights, and play through every one of those games back to back!
 
 
Surely no harm could come from such actions.

Have you played any of these yet?
