The PSP is great for fighters, barring its tiny controls (Well tiny for me because I have big ass hands). I just wish my control numb would stop moving on its own even when I don't touch it. I really want to get a Vita just so I can play PSP games upscaled with a real analog controll stick. As for Dissia, I played a demo and liked it but couldn't get into it. I haven't played any FF other than X and I still couldn't get into it.
