Yeah, though with it only being 20-30 mins for a single race, probably quicker if only with experienced players that are motivated for a shorter game, or with less players, providing less cramped quarters. Reducing the length of the track is certainly an option, as is extending it, but pretty sure adjusting the size/contents of the player decks to maintain the balance of resources would be needed. There are actually some posts about 'shorter stages' on the boardgamegeek website for the game. As for longer stages, I'm sure there could be some improvisations made.

I did find it an interesting choice for a game, but was quite pleased that it works as well as it does.
