The problem with Puerto Rico is that there is often only one optimal move -- and sometimes that optimal move doesn't do anything for you, it only spoils someone else's strategy.
But that's probably the best part of it. Your Puerto Rico skills go way up when you realize it's a game of relative advantage and not absolute advantage, and that your best strategy involves keeping careful tabs on what your opponents are about to do and either thwarting them or incentivizing them to do things that are good for you.
It's like chess or go in that you need to keep careful tabs on your opponent, but can be played with 3-5 players.
