Hm...I didn't know SSMTs were given a one word moniker...
I snake.
I'm curious as to how you'd disable snaking, but not MTs. Unless you give the option to completely disable MTs. Which wouldn't bother me.
I would like battle mode to have larger size arenas, like the older days. A few more arenas, and use larger engines. 50cc (hell, it seems slower than that) makes it next to impossible to just dodge a red shell. You can still block easily, but dodging is another matter. Overall, I just hate the sluggish feel of battle mode. It's still fun, but I think faster would be more fun.
And go back to five races per cup like the SNES.
