You can never go back (game nostalgia gone bad)

Not every game is a timeless classic like Super Mario World or Ms. Pac-Man sometimes the passing of time renders some of your favorite games nearly unplayable. Which of your childhood favorites are now unplayable ?  Here are a few of my favorites as a kid:
Spider-Man: Maximum Carnage(Genesis/SNES) - What is not to love? It came on a red cartridge and you could play as Venom. Unfortunately it is a button mashey brawler that gets extremely boring after the third stage.
Kingdom Heart 1 and 2 - As a teen I loved the odd mix of Final Fantasy and Disney in an action-rpg setting.  When I tried to play the games last year I was taken back at how awkward  it was to cast spells and how sappy and needlessly confusing the plot was especially in 2. Top that off with the fact that you play as possible the most annoying protagonist in video game history and that you have all these awesome characters join your party that you can't control. I would of killed to swap out Sora for Auron, Jack Sparrow, or Donald Duck.

I also agree Maximum Carnage isn't particularly good.

Not every game is a timeless classic - I agree. The ones you mention aren't. But many are.

I hated KH 1 and 2 when they were new, so w/e. Also, how are they childhood games? Unless you're like 14... 
 
Unplayable? Hmmm, I don't know, a fair few have aged badly but I guess the only one i'd argue is downright unplayable would be Castlevania (N64) or perhaps the original SFII. Not because it's a bad game, not at all, but because the later versions of it make it utterly obsolete.

Its still played in tournaments, you know. "

Tekken. I used to play it with my brother for hours on end and it was an absolute blast, but if I go back to it now, all I can think of is how stiff, clunky and mashy it is.

I'd say Final Fantasy VI through X are classics. I'm sure I'll replay these games in 10 years from now. Especially X.

I used to play this game all the time with my friend.  I popped it in like a year ago, and couldn't believe how badly it played and looked.  "

I tried playing Tiberian Sun again a few years back. It was truly cringe worthy. Also, GTA Vice City. It's not even that old but I already consider it to be completely unplayable.

You don't like the faceless Popeye arm people of Final Fantasy?

FF7 doesnt hold up AT ALL. Then again its a known fact that 2d games hold up much better than early 3d ones "

ff7 is way overrated the story was either translated very poorly or was by nature confusing.  the graphics definitely does not hold up this one is definitely unplayable.

I found Maximum Carnage playable(played it last year) it was just ridiculously difficult for me. I think being unable to go back is one of those things that depends on your mind set. A person like that probably wouldn't play a Wii game because of lack of achievements/trophies. I'm currently trying to play through Fallout 1. It's incredibly archaic but it's interesting to discover a world I never played growing up. Do I get pissed and turn off the game when 20 scorpions gang up on me? Yes, but underneath the weird aesthetic is a decent game to discover. So, I think any game is still playable, it's just you need to get into the mindset to want to play it.
