The Ascendancy of Culture

This one is a toad for me but I'm itching to play it. I even have the Ferengi expansion.

The Ferengi can be tough. If you have a group willing to make deals (think a Dune group), they can blossom into this incredible threat that people can't cut themselves off of (just one hit...) But if you don't have a group willing to deal, they can be quite frustrating, and play kind of like a Federation without the hegemony and phenomena bonuses.
