How many GB is The Royal Cosmonautical Society?

0.49 GB

That is less than the typical Adventure game, which needs about 5 GB.

Leave at least 6 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

Enjoy the rewarding challenge of becoming a qualified Cosmonaut. Gracefully pilot your ship through multitudes of challenges, finding the perfect trajectory all the way to the top of the leaderboards.
