To tell you the truth
When I first played Mario Kart 64 with my friend, Battle Mode was the most fun I had with the game
I had a similar experience, except mine was filled with pure hate and rage. I suppose it was fun, in a sadistic way. The other option was worse, since everyone would always pick Wario stadium. They'd always go for the thunderbolt so they could cause people to fall of the big ramp jump and have to start from about half way back. So then nobody would attempt the jump and everyone would just stop a few feet from the ramp until someone gave in. At least in battle mode we could actually finish a game without having everyone rage quit.
