@bygwyllay Those are the only three scenario options available for the base game. If you want to play Seafarers, Cities & Knights, or combinations of those you will have to use a sun to activate the single player mode for the expansion you want to play, or buy the expansion. I hardly ever play the base game.
@borbes True, but it also doesn't say the maximum number of ships for Seafarers (15), or roads for Inkas (7), etc. The physical games have a content list on the box. For the standard games, Catan Universe uses the same rules and pieces.
