Here's a pretty good review for anyone considering getting the game, but not sure yet. I would say no to the current price tag if you do not know how to enjoy a game like this fully. The game has great potential to be even better, but falls a bit behind with bad decisions, you can hear his dissapointment because he actually enjoys the game but is kind of held back from it at the same time.
Personally, i do agree with him quite a bit on all the challenges etc, they are very opposite to what the game is suppose to be, i do enjoy the wingsuit challenges though. And i can enjoy repetition quite a bit, its almost a shameful thing to admit that grinding things can be the enjoyable part of certain games for me. The most enjoyment i got out of wow last time i subbed (during MoP) was fishing, and i fished a lot, enough to get me the title and mass overload my guildbank with fish junk.
Unsure of buying? Wait for sale, and be on the lookout for mods, a multiplayer mod alone could change up the game a lot.
