Uh, does Rocket League count? XD
I have some 6000+ matches played in it.
Besides that, I played tons of Heroes of Might and Magic and Diablo.
When it comes to games with a world that doesn't change, Fallout 2.
I have a hard time sticking to just one game and repeating it. I hate doing that. Unless it's very different every time I play it. It applies to real life as well.
