What AAA first party game from MS doesn't have microtransactions like this? These are MS's biggest franchises Forza, Halo, Gears all with mtxs. Rare was converted to a studio working on microtransaction avatars during 360 and now microtransaction GaaS games for game pass.
Why couldn't any of these studios you listed make a xbox Series console launch game?

They are concentrating on a platform agnostic game release and MS couldn't care less about what you play on just as long as you are paying the sub and spending in their games. EA access was also full of games without a focus on MTX initially but what do you think this model encourages after the initail building the library? Be honest.
