They're all Ubisoft open world games. They all use the towers to unlock side activities, auto fail quests and whatever else. The difference is The Crew is online so you see other people driving with you. It's very enjoyable to be honest. Far Cry 4 would probably be the one you'd enjoy the most unless you like driving around. The difference is one is a technical mess and uses blades (and few auto-aimed guns), one uses guns and one is all cars.
