There's no game to play at the moment. The game is still in pre-alpha. We're just wrapping up domain and settlement selection where nobles and aristocrats pick their lands and settlements.

No dates yet on a playable version but that's the next major milestone!

p.s. I suggest reading this announcement about the phases of development that lie ahead and coming in the near future.

The ''game'' is played in discord in the forms of politics and planning, Buying anything now can just give you rights to a settlement at launch, There is nothing psychical to play at this time and will not be for awhile longer
