We played with the Legends, Through the Seasons, Corrin Evertail, and Extra Extra! mini expansions. I haven’t played with the bigger expansions very much, but these little modules definitely make the base game a lot more interesting without adding too much more complexity.
It’s a worker placement game and one of those “play alone together” games. Only real interaction is the other player(s) taking an action or specific card you had plans for. Can only talk to base game but plays really well in 2 players I think, played just with my wife a few times.
