I'm strongly considering getting this, but I'm a bit worried about the fiddleness? Fiddlety? Whatever.
How many pieces have to be moved or manipulated every round?
Zero have to be manipulated every round (which is the whole point of the wheel), but there is still fiddliness every time someone picks up resources as well as when those resources are converted. If you've played Le Havre before, then it is very similar in terms of the resource conversion and chits used....
Uwe took it to another level with Le Havre: The Inland Port, which uses the wheel AND a tricky tableau to eliminate almost all fiddliness.
