I just hope FFXIII is better than FFXII. Twelve was the worst one in my opinion, and I'm tired of having a main character that looks like a Thai ladyboy. I guess I just have such high expectations for that series that I'm constantly left wanting more. I loved 7-10, I never touched 11. 12 just had... the worst battle system I had ever seen. The story was only mildly interesting, I never even finished it sadly.
LMAO, I didn't know whether to get turned on or say "Huh?" when I saw Tidus in FFX. I think it all went to shit after FF9. The new battle system blows my balls. As for Kingdom Hearts, I played and completed both and the first one was the one that had all the magic. The second one was a "eh, whatever" at best. I want see Mickey kick some ass again!
Another thing I'd love to see is new Fallout 3 style and themed game. That was one of the best games I've ever played, I loved the post apocalyptic feel to it. The map was immense, the character incredibly customizable, but the story was just too short on it's own, the ending was a massive letdown. Everything else was amazing. I'd love to see something else along those lines.
I like the movies, I think they're an amazing aspect of the game and something that FF is now known for. In terms of story, I loved FFVII but I never got into it a lot because FFVIII was the first one I ever played. Story wise however, FFVII and FFIX take the cake IMO. FFX was interesting, but I've never had an easier boss battle in my life, and Seymore just was... A shitty character all around. It seemed like he was an attempt at making another Sephiroth, but it failed miserably.
