Personally I’m big on Sonic Robo Blast 2 Kart. A mod of a doom mod that plays like super mario kart pushed to it’s absolute limit, with a community that has added most characters you can think of, a million quality of life changes, and some things that crank it to 11 for me, like the blue shell equivalent moving just slightly faster than your top speed, so if you play perfectly and drift dash nonstop you can keep it just barely tickling your butthole but not hitting you.
