Picked this up last night, gave it a few hours today and so far I dig it. It reminds me a bit of Just Cause 2. Cool story, great looking graphics and good voice acting.
Load times are kind of slow on 360 but other than that (and the usual 19 Ubisoft Play menus I need to cancel/decline every time I start it..) no problems.
Is it better than the second one? I couldn't get much further than an hour into that game. It kind of bugged me that it was so different from the original.
