I hear the voice calling me, save me everyone lol
The Ultimate Edition adds new cards, expansions, and a 1v1 competitive mode where one player can play as the Imperialists going against Captain Nemo. Honestly, that last bit is the most attractive to me.
For those interested, I've seen a comment recommending people not to get the add-on for the cloth bundle, which includes a cloth map version of the board. Says that there's a potential for slip that will move around the pieces on the cloth board. It was only one person commenting on that so please do your research!
Who here's going "UGHHH why are you sharing this Phil???"
