Sega admits Sonic is falling

[Flare]

Yoder, I believe the hoverboards are used to one give all characters - some of which are slow, some are really fast - an equal chance of winning. But also Sonic has several times taken to snowboarding of sorts and people always like playing these parts so its possibly why they use boards.

Sonic Team have a big thing about boards, remember the original intro to Sonic 3.
