For me it was the "Twisted Metal" series. Me and Craig would play those games for hours, even days on end. I mean shit, how does it get any better than driving ridiculously fabricated vehicles, manned by ridiculously fabricated characters, around ridiculously fabricated arenas, blowing the living crap out of each other with ridiculously fabricated weapons? Every boy's dream, right? But it was simple. Everything about the game-play was basic, and easy to figure out and master.
