I was paying this game which had a story of the creation of the world with different figures that helped create the world in this game. This is inspired by a set of books and might have its basis in avodah zarah. In the game you help one of these figures do something. It is not actual worship you just help him with something that would save people in the game.
Am I allowed to play this game?
Also is it considered Avodah Zarah or Shituf?
I don’t think that playing the game is actual avodah zara, nevertheless, it is associating oneself with avodah zara concepts, and we have an obligation, to distance ourselves from connection with such things. Therefore you should not play this game.
