Finished this game today. I liked it a lot, not sure how it can GS can justify a 5.0 for it. I mean it did feel like a budget title to me but a good budget title...so i guess I could see being a little annoyed if you payed $60.
Guy in the GS review said it was repetative but its really no more so then Assassins Creed and in fact, does a better job of providing the illusion that its not repetative unlike AC. The guy said the camera was bad. I had no trouble with it at all, seemed very intuitive unlike Star Wars Force Unleashed which seemed unplayable but somehow got a higher rating.
The graphics were very nice and had far less glitches in it then Mercenaries...though there was some pop in and some slow down in the bigger battles. (and they were big battles).
The mini-map was not too good. It was hard to tell how close or far you were from an object and whether it was above or below you and the main map wasnt helpful with that either....... of course I had this same issue with Fallout so thats not really a sign of a quality game.
The voice acting was well done IMHO. The music (when it was there) was nice. It seems like they forgot the mob portion of the soundtrack or maybe it was just very muted like the music.
Seriously, if they had broken the sound into dialouge, music, special effects all with their own volume setting and then balanced them better it would have helped with the experience. Throw in a little stat tracking and a few more enemy models and things to find in the wilderness (and maybe a sprint button) and you have yourself a quality title. Oh, I also want the button from fable that pulls the orbs to you so I can collect more and use my magic more

.
Oh and the GS guy who reviewed it thought the story was confusing. I found it quite straight forward. Was it a masterpiece? Well no, but it was at least as good as Crackdown or Mercenaries... or even Assassins Creed (though I have hope that AC story will become more interesting in the sequels).
