On a relentless FF bender: after VII, where to next?

Looks like you got a lot of responses already, but I'll throw in my opinion if you wanna read on....

Final Fantasy I - I think you said you played this, but yeah, this game is very challenging (at least for me) and it's a lot of fun.

Final Fantasy IV - Seconded as being one of the best games ever. Seriously, more plot twists than you can shake a stick at.

Final Fantasy V - Awesome game with an awesome class system. It's a pre-taste of Final Fantasy Tactics if you decide to pick that up. And yes, the main character's name, by default, is Butz. Pronounce it as you wish.

Final Fantasy VI - This is THE FINAL FANTASY GAME. This game cannot be beat. With a deep story, awesome music throughout (I'd have to say this is the BEST boss battle music here), and a utterly evil villan. You'll seriously want to punch this guy in the face when you reach the end.

Final Fantasy VII - Awesome game too, I guess you're already playin this one.

Final Fantasy VIII - Pretty good game, I like it, though not as much as others. A little different, I'd have to say, but good, nonetheless.

Final Fantasy IX - I liked this one a lot, but some people don't like this one. I dunno. It's kinda like a return to the "fantasy" world with the return of the traditional Black Mage, Moogles, and Chocobos after their lack thereof in Final Fantasy VIII.

Take your pick, they're all really good.

Jam it back in, in the dark.

I didn't include this earlier, but yes, Final Fantasy Tactics is an EXCELLENT game. Next to Final Fantasy VI, it's my favorite.

There's nowhere I can't reach.
