Yes, all Season 1 and Season 2 maps. Season 3 content is coming soon but not on BGA. In a few months, Season 2 content will be removed from BGA to encourage players to play directly on the mobile video game which is in development and should arrive before the end of 2023.
Would it be possible to have the Season expansions available on BGA, but perhaps only for Premium members? I love playing on here since the asynchronous format and computer screen layout is so easy to use.
Also, I'd love the ability to be able to choose which expansions to play with. It would be nice to occasionally narrow the selection of expansions we play with, rather than just all or nothing.
