Regarding the way Supremacy 1 allows/restricts access to game rounds we deliberately deviate from the S1914 formula. Especially in the beta phase of the game we want to group players into the same game rounds - hence you can only choose the map type via "JOIN" and not the specific game round. In the future we also want to introduce a mild form of 'match-making' which means that the details of the specific game round you will join (like the map fill rate) are not even 'known' before clicking "JOIN".
It's bad decision, because we must see available maps with number of players and players side for battle maps like Veterans Front.
Besides that can we create maps with password for friendly Veterans Front games with own numbers of players for sides and starting after full with admin helping?
