Im going to reserve Judgment to be honest having only done 3 missions in single player and played some Exo Survival which is extremely tough on your own.
Its better than Ghosts which isn't exactly that taxing,but the engine as usual is really showing its age,in some shots the game looks lovely and then in others very low texture detail and flat looking areas.
Not touched the online multiplayer so no comment,will i be still playing this in 2 weeks time when Far Cry 4 ships���A resounding No at this moment in time
