I was disappointed....

The first game was a lot better. get it. if you love the first, consider this one. Personally, I miss the art of the first. and also the game feels a bit clumsy.
Controls are great, gameplay is smooth, I just dont think its as good as the first.
If you want with fun combos and you have already beaten all of the Gamevil games and the first SEED, then consider this game, if not, start with those.
Again, just my opinion.

Chillingo: PLEASE make more RPGs like the first SEED, you did a great job on it
