I'm not 100%, I just remember Mike bringing a Dune board game at some point, and me winning even though I got destroyed in the first turn (so its a game I'll never play again as I'm 100% ). I think it was Mike, me and one other (maybe Matt?). So whether it was Imperium, I honestly don't know.
I’ve read the rules and am filled with foolish confidence. I don’t know about Matt but it looks like something he’ll be able to pick up pretty quick.
