Looks like a nice make your own fun and duration kind of game. Some board games just take too long no one ever wants to play them as they are not finished in time. This one looks like you could just shorten it quite a bit if you needed to. Get a quick game in and call it a night.
You always find some interesting ones. I would have never thought someone would make a racing track one like this with bikes for players to move around.
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.
