I'd like to play S.K.A.T.E. in skate.

Roshambo emotes would solve this without needing to integrate it into the Throwdown feature. But if not that, then maybe a Throwdown option to invite one other player to a game of S.K.A.T.E. If you set it to three-player or more then it assigns the set order randomly for fairness.

I'd even like to see a version of 1-up come back.
