I thought I'd go for the first laff boost in Kart Racing, but I've got 6 trophies, and have a few questions on the way to get the next ones.... What's the difference between, say, Corkscrew Colliseum and Corkscrew Colliseum Rev? What does the "Rev" mean? How can you tell how many of which race you've run, other than keeping your own scoresheet at home? I thought it would be like mini-golf, where it would say "You have completed 4 urban racetracks" or something. Is there any advantage to the different starting positions? Is it better to be on the far left? far right? inbetween? Do you have to enter the Grand Prix at any time to get any of the trophies? Does each track of the circuit count toward your requirements? That's all I can think of right now, racing is my next laff boost challenge as I've got the first mini-golf and can clearly see my way, I'm stuck at ultra rare fish, with 5 left to go, I got the 8 bean flowers, and I'm nowhere near maxing any boss suits. I don't seem to have any problems finding other racers, Sunday mornings seem pretty well-attended, and have won my fair share up to now. Who's the Kart Racing Guru?
