I feel like nothing that's day 1 on game pass gets much marketing. It just kind of comes out and then it's free and I guess that is the marketing for selling the game at a later point?
For whatever reason game pass games increase sales for games as studies have shown. I still don't really understand that. Why would you pay for something that's free to you for at least the next 6-12 months, especially when a lot of this stuff is single player that you'll clear in a week or two, but good for the devs so not complaining.
