I was playing Gears 1 co-op last night at a friend's house and the game was still flawless, it still looked great and the controls are still some of the best in it's genre.
Not to long ago I wanted replay Oblivion, which is one my favourite games ever and I stopped when I was an hour in because the game didn't look as good as I remembered, the controls are kinda stiff, the loading is ridiculous and the whole thing felt like a chore.
Some games are so well built they can stand the test of time, some aren't. Most of the N64 and Gamecube games I have are still very enjoyable, but outside of a handful of games (God of War, MGS3, Yu Gi Oh: Dual of the Roses etc) the PS1 and PS2 games don't stand up as well as they did all those years ago.
Got any games you'd like to talk about?
Note: It'd probably be more interesting if you can list some games from this generation as well, don't have to, I just think it might be interesting.
Bet with Conegamer and AussieGecko that the PS3 will have more exclusives in 2011 than the Wii or 360... or something.
