Yeah this game was a total surprise to me and really the only thing in the Direct I got excited about.
I've loved Pacman99 and Tetris99, and only play Mario35 a few times while it was available but that was cool too. Super excited about a 99 game for Fzero!
Played the game a bit today just expecting the original game but made to accommodate 99 races, but they actually added a bunch new stuff for this game. Very cool! Although this game makes me reallllly want a FzeroX-99 game haha, but I'll get plenty of Fzero gaming in now on NSO between this and FzeroX. This game really breathes in new life to the original Fzero which quite frankly pales in comparison to X and GX.
This also shows that Nintendo knows fans want Fzero so I have hope we'll see GX either on NSO or an HD remaster at some point in the next few years and maybe we'll even live to see a new Fzero game haha.
