I'll tell you one flaw this game has: it isn't gripping. I haven't played the game in a week, and I couldn't care less. This is despite the fact that I finally got out of the boredom that is Cocoon, and am finally down on Pulse which is much better. Therefore, you'd think I'd be eager to progress the game to see what's next in the vast world of pulse, but, well........meh. Its f#@kin' boring.
And I absolutely LOATHE the weapon / upgrading system. I will say this, I by far prefer XII's weapon system, since some people have turned this thread into a silly "I think XII is better than XIII, here's why, I am right you are not", and vice versa argument.
