Been playing Horizon 3 on xbox and pc since friday and boy, what a game! Well done!
Only issue I have run into is that on PC there is some lag when I am in the upgrade area upgrading my vehicle and also when on the auction house. Not huge issues though, no crashes on the pc version so far.
I love the improvements from Horizon 2, excited to rock some coop campaign with a few friends once they hop on. Now back to some more races!
