Yes, they are very different. If you put a casual gamer behind each, they probably wouldn't notice or appreciate the differences. Both are different but good in their own way.I normally always use cockpit view in racing games, but for GTS I have to use that front bumper cam. The visibility is really tough in this game in cockpit mode.
I splurged and got myself a Logitech G29 for PS4 so I am jumping back into this. Had some Amazon credit burning a hole in my pocket. I have pretty much played the heck out of Forza 7 and want to switch over to this. As odd as it sounds, both games are actually quite different.
I would get a wheel, but I don't have space for it in my condo. When we move, I am going to move up to a wheel for sure.
