The Aetherlight is an episodic game that is released in seasons. Currently we have Season One available which contains Episodes 1, 2 and 3.
By purchasing a Season you gain unlimited, perpetual access for 1 player to all the content for that season. (You could also consider buying a Season One Family Pass which gives 5 players access to the entire season!) There is no time limit on any purchases from our store, the purchase unlocks the content for you to play.
