My personal favorite is the origional Pokemon games.
Generation one was the BEST pokemon game they had, the second generation was ok but then from beyond was BS. And for the best old game, hmm well you guys are going for the really old games but the PS1 is still really old so i'll have to say my favorite game for it, released exactly 10 years ago, [url=http://en.wikipedia.org/wiki/Brave_Fencer_Musashi]Brave Fencer Musashi! That game was filled with lols along with a great game, everyone and everything was named after food! The game took place in the 'Allucaneet Kingdom' (lol) where you had to rescue Princess Fillet (lmao) from the Thirstquencher Empire (XD) who's leaders name is Flatski (X'D) theres alot more funny stuff, but that would take too much time and thinking.
