Hey guys! This is my first post here an I just have a quick question. I've seen the Lets Play's where the AH crew plays GTA V with their community members, like race maps or cunning stunts, etc. I've wanted to join in when they do this sort of thing but I don't know which platform they're playing GTA on.

Does anyone know which platform they're playing GTA V on?

Thank you so much for your help in advance!!! c:
