Tom Vasel's Summary:
I can recommend Il Principe, but only conditionally. If you’re looking for great components, nice theme, and an easy-to-understand game, then this isn’t it. It is a collection of unique mechanics tied elegantly together to produce a nice game. My biggest fear is that Il Principe is a forgettable game – one that’s enjoyable now but will be forgotten in a couple years. It’s the flavor of the month, and perhaps lack of theme will kill it in the long run. Most certainly it is a “try before you buy” game.
