The controls are “fine” for the most part. If you were on an Xbox controller it would work. Space Battles in Battlefront II are an improvement, but the same treatment was never made to Battlefront 1. If I had to complain about anything, it’s that the auto aim needs to be more sensitive and when you blast an enemy it auto locks on them like the console games. Mouse and keyboard this would be annoying but on controller it’s necessary.
If you’re still considering it, you can get it for like $10-$15 on GOG. Same price of steam but DRM Free, and it’s almost always onsale.
