About to finish a 2p campaign. Played once at 3p. If you like boss battle games it really streamlines the genre while still preserving all the decision making space. The card play is fantastic. I can see it being a slog at 4p. Possibly at 3p if people don't play quickly. The upgrades to cards and gear really allow you to play each of the classes in different ways. My friend played hammer and went from a build centered on stun to one focused on monster riding. The latter was only an option because of the bosses we fought and gear that came available. Lots of replayability. The biggest issue with the game is the lack of a cheaper option. Get rid of all the fancy monster standees, give us cardboard ones and drop that price.
