Does anyone have an idea when the extensions will be available to play online? Maybe Catan Universe forum moderators can answer this?
What do you mean? As a Beta tester you already got some ingame currency and can buy three extensions for free.
same question here-just to be clear extension is not expansion. Extension allows for 5-6 players. Expansion provides different boards.
There are plans for the implementation of Multi-Catan which is for more then 4 players after the official release. But for now we are focusing on the board game version (for up to 4 players) and the Catan card game.
