I'd have to say Metal Gear (Solid) is mine. I'm trying to think of other series that have a bunch, I know Nintendo has their games, like Zelda, Mario, and what have you, then there's Final Fantasy... Well, yeah, I guess mine would have to be the Metal Gear series. I'd like to know what yours are, and maybe that'll even help me recall some other great series of games out there. Oh, and I guess the reason behind me liking the Metal Gear series the most, especially the Solid games, is because to me, they're all consistently fantastic, and interesting to me, I can't say the same for others out there, or at least I don't think I can. Oh yeah, there's Assassin's Creed, but to me, those are almost episodic in a way, as if from AC2 to Revelations was one game, and I still think MGS is better anyways, but still, there's that.
