Meh. I'm back, soon I know.
Mario Skateboarding? Dah hell, we don't already have one?
BUT, this version of Mario Skateboarding is for the Nintendo 64! Since this is fanon, this game will be released in 2001, using the Tony Hawk's Pro Skater Engine.
The game works like this, there's two modes: Racing and Record Break. In Racing, you race against other 3 (you can change the number of CPU's) CPU's in several tracks, pretty simple. In Record Break, you battle against other player or a CPU, to see who wons more points.
There's 8 characters at start: Mario, Luigi, Princess Peach, Princess Daisy, Toad, Yoshi, Donkey Kong and...
MAMA LUIGI Wario.
You will unlocking other characters when you beat Cups at the Main Story Mode, there's 16 unlockable characters: Waluigi (YAY), MIPS (yeah, strange I know), Donkey Kong Jr., Shy Guy, Koopa Troopa and the rest I will reveal later.
The cups works like in Mario Kart, overall, this can be called "Mario Kart-boarding"? Nope. That's all for this game, I think I explained it very well, so. Bye.
