That's cool, but in MS's case I see this benefiting 3P games not in GamePass more than their own games, so it's a bit limited in that respect. Reason being, if you're getting all their 1P games Day 1 in the service anyway as well as quite a few 3P indie and AA games, why would you need to demo them? You could just download or stream the full game and decide if you want to sink more time into it or not.
I guess what I'm trying to say is it seems a bit redundant for MS to be doing this considering their angle for GamePass, as well as having EA Play in there and potentially Ubisoft+ as well. Unless....
certain things are changing with that current GamePass approach
