As a heads up, speed is increased significantly by following the official auction rule: When you land on a property, you have the option to purchase it outright; or if you do not purchase, the bank will then conduct an auction of the property.
That's what I've heard, but it only solves the "getting all property bought up" problem. The other bottleneck is "getting some player to trade away the last of a color", which seems to be unchanged, right?
