That why I also liked X-2, despite the rest of being complete crap. But I will always HATE XIII and that game did it for me. No more FFs.
The job system in X-2 was great loved it. I did however like the rest of the game but it was a strange departure from X it seems more like "girls just want to have fun" that's the theme I got from it anyway.
What was so bad about XIII? I hated how the game was so linear but it had a decent story, I will say its not one of the best ones but it was good. It had one of the series best and most memorable characters, Lighting.
To the post above, the modern Final Fantasies are different yes and they change things but each Final Fantasy game is a different world and its not a continuing series minus X-2 and XIII-2 of course. I detest MMOs wo I am not including XI or XIV.
