I love racing games because you have to really think about when to pass, when to do your refueling etc. It requires a lot of skill. My driving is not always the greatest but I do pretty ok. The rush of outmaneuvering your opponent is fantastic.
Recently I've gotten more into the strategy part of racing games. Motorsport manager is one of those games that is a different kind of racing game but I enjoy the heck out of that. I wish more games were made like that.
