Have it on PC with a pretty decent video card, so haven't hit many of the framerate issues console players have been having.
Fun game, missions are boring and repetitive as hell though, I'm just mostly doing the challenges to level up my equipment and running around blowing stuff up. Can't see it holding my attention for longer than a week or two, with the exception of the wingsuit, it's basically just cause 2 with a bigger world. Not that it is a bad thing, but given the world is so big now, it's highly unlikely I'll finish it.
The wingsuit is damn fun though, my record flying is at around 10 minutes now, once you get used to it you can shred apart bases pretty easily.
Basically if you loved Just Cause 2, you'd love this one. It just may not hold your attention as long as it did previously, the dialogue and story are pretty cringeworthy and feel much more dated than it did in 2010.
