Aye, it wasn't bad, but for a Final Fantasy game people have certain expectations that this game didn't quite deliver on. I personally would have given it an above average 7/10 overall, mostly due to graphics, environment (visually, I'm a big sucker for things having a large general scale to them and FF13 does have some big set pieces) and combat design.
Oh and I apologize for the length of my previous post. I trimmed it down about 30%, and I could rant about so many more little bits of this game that bug the hell out of me, but that just comes from me being nitpicky when it comes to games. Hell, I did a pretty long rant against FF7's terrible story and still said I liked the game overall. Even FF9, which is one of my top 10 games (largely due to the characters) has a story I can rip apart into tiny little bits. Take any big game and it's going to happen if you think too hard.
