We have run kart racing at every LAN party I can remember, and the problem has always been that the good ones cost money. SuperTuxKart solves that without asking you to compromise much. The handling is loose in a way that reminded me of early Mario Kart, which means skilled players do not immediately lap everyone, and that matters when you have mixed skill levels in the room. Set up a round-robin bracket, rotate people through, and you have a solid hour of content without anyone needing to own anything. It will not replace Gran Turismo 7 for serious racing, but for a budget LAN it is as close to consequence-free fun as you can get.
