The garry's mod of vehicular physics games, and then some. I've probably had my most enjoyable gaming experiences of ANY game and system just messing around with this game once I got the hang of it. It's one of the first games I bought on my steam account and I didnt have a good enough system to play it until about a year ago lmao which is why I dont have much playtime on it, because now I don't really have time to game anyway which kind of sucks. But the off chance I get to play this, its so amazing, everything I've ever wanted. Its so much fun to get creative and the content creation potential lies within you. Some of the creations utilizing this tool are INSANE. If you have the system to run it and you don't mind a slow start to get the hang of how to actually play this game, then definitely go for it.
