Oops, my bad. I wasn't sure on what the expansions were. I had the original version without any expansions a long time ago, but the game play got a little stale for me.
Yeah, we'll be going with Rebellion since it's the most recent expansion and most people have it. The Forbidden Worlds DLC though.. hmm... I think only the host needs to have that to run a game with it, we'll check.
