Almost unrelated, but I also learned what was capital efficiency and payback period after playing Monopoly for the first time in years. Long story short, when the properties were eventually sold out, I burned my cash flow to buy more of them to other players, at a high price, when they needed money (it would also allow them to play longer) My logic was that by owning the most properties and by building houses and hot…
There's one monopoly that matters in Monopoly: the houses themselves. The game only has 32 houses. If you get two 3-property monopolies and build four houses on each one, forgoing hotels, you have 24 houses and everyone else is fighting over the remaining 8. If you get max out houses on two 3-property monopolies and a 2-property one, the game is yours regardless of what anyone else has.
I usually did better playing this strategy. Even though winning with houses on park Place is more fun, houses on Mediterranean ave are more certain.
