It’ll be the cheapest place, by an absurd margin, to play Baldur’s Gate 3.
If I’m not mistaken the only reason it’s not already on Xbox is because Microsoft insisted it needs to have shared screen on all models, which proved to be problematic and eventually impossible on S, but they refused to release it on X in the meantime.
Basically it’s very much Microsoft’s own doing.
We don’t know that it’s impossible on the S. It may yet happen sometime after launch.
