The system is still “PC” in this case, even if technically the platform is different. And since you have to log into your account with their service, they can easily confirm that you own the game.
I don’t have to create an account to play Slay the Spire on Android.








You could have the PCs be in service to an evil wizard or overlord, and just take any regular plot and give them the baddies’ role.
You could have multiple factions in a city, like noble houses, and give them some sort of goal to accomplish in that context. Think Game of Thrones or the drow in Menzoberranzan.
You could have them doing something “good” but with a “the ends justify the means” mentality.
