Alot of people will say Grand Theft Auto.

I say Splinter Cell or Hitman.

God Of War II

That is such a long game.

Well, it does own. I still play it honestly. I am waiting for the new one on the PSP :D!

I played it once. Awesome interactive and cut scene fights.

You feel like you are in the movie, the boss fights are legendary. But that's me, I love hack & slash and bloody battles :P

Hell, I'll enjoy any game that has a character with a huge sword!

But it might not be appealing for other :P.

Well I'd say GTA was definitely a hit, but it wasn't the best PS2 game series. However, I'd say almost every single PS2 owner had some version of GTA, and most of them had at least two.

Dead 2 Rights was another good game.

Yeah, the end of God Of War 2 was kind of dissapointing, it was getting to the best part... then bam the game ends, leaving you to wonder what's going to happen next.

-_-

Fighting Zeus was like wow.
