Monopoly has one great rule (or lack of specificity), that it doesn’t put any restricting on when you are able to trade (doesn’t even say it has to be your turn!). This creates a great ten minutes or so when most of the properties are bought and people are making interesting deals with each other.
Everything else in the game is bad because there are very few interesting decisions to make. The dice tell you where you go and the space you land on tells you what to do. Strictly you “decide” whether or not to buy an available property if you land on it, but it’s virtually always a good idea. In the rare auction case you can decide your bid. You can decide which order you mortgage off your properties if you are out of money. I think one of the chance/CC cards has a choice on it? Even buying houses is kind of dull since you have to build them evenly across the block.
100% true. Note that I was responding to someone who called it quick and fun, so the lack of choices seemed like a relevant point there.
