Those games I bought and loved:

FF7, FF8, FF9.
Parasite Eve.
Gran Turismo 1/2.
Silent Hill (this game was one of the few that scared me).
Resident Evil 1-3 (2 is the best RE imo).
Diablo 1 (its addicting as hell, especially 2 Player mode on one screen).
MGS ofcourse which you already have.
Tomb Raider 1 and 2 (2 is the best one)
Tekken 3 (best one).
Dead or Alive (Bouncing tits in 32 bit and atleast as good as Tekken 3 imo)
And Command and Conquer Red Alert in 2 player mode SP wouldn't be much fun today (Needs 2 PS1, 2 TV ,1 Cable but it was totally worth it back then )

With those games I had the best time.



Edit: Forgot certainly a few games, like Alundra, you should totally get that.

As expected, I'm being flooded with games :) And as expected, a lot of RPG's (nothing wrong with that)

I guess I'll have to look at what games are mentioned the most.

As for now, I'll start out with oddworld, the final fantasies, Tekken 3, and the crash and spyro games. And Parappa the Rapper, since it's dirt cheap on Ebay.

A question. I was thinking about getting a twisted metal game, since they are supposed to be fun multiplayer games.
But there are 4 of them. Which one is the best?
