That Snow Moon is a space opera inspired by a popular movie involving space and battles, while not actually infringing upon intellectual property. 

In the game, players divide into two teams: Liberation and Dynasty. Liberation throws their cards facedown onto the field, trying to assemble a particular set of cards. The Dynasty drops their cards onto the table, trying to land on the Liberation cards to reveal them and take out important cards from the Liberation.

The Liberation tries to bluff and disguise what they're doing, while the Dynasty tries to outguess and crush them, which each side uses its unique special abilities as best it can.

Never forget that snow moon: it's a space station.
