Halos been a franchise for how long now? Last of us is a much younger franchise. Theres last of us, game of the year edition, the remake, they sold the dlc serperately from the game, supposedly theres supposed to be a movie, there was the last of us on ice and now a vinyl disc of the soundtrack and theres more. Halo has been milked sure, over three generation and over more than ten years. big difference here
