I'm about 20 hours in (almost have my skell) and it is a very fun game, but it has a lot of little irritations. Lip sync is horrible, music is either really good or god awful, text size is too small, and the social stuff is just confusing.
Still, gameplay is solid, story is slow, but it seems like it just kicked it up a notch so I'm intrigued. I'd give it an 8.5 as of now. Good game with a lot of little annoying things.
