Oh they look far more awesome in Dissidia than in anything else, there's not even any contest with that. I hate being disagreeable and all, but I find the chibi 3D appearance really difficult to take seriously. It just doesn't really seem very awesome at all. I really wanted to have cool full-grown characters instead of 12-year-old cosplayers. Sorry.

However, at least they decided not to go that route when doing things like Star Ocean 3 and 4, or games like FF VII, FF VIII, FF IX, FF X [even though I didn't care for this FF], FF X-2, FF XI, FF XII, and currently they aren't doing it for FF XIII either.
