I don’t think there’s a single person in the world that wants to play android games or use android apps on their Xbox.
I remember when Facebook was on the 360 too. Didn’t last long.
there are a few good android games that also work flawlessly on contoller.
example Max Payne, or all the GTA games, including Chinatown Wars.
the issue is tho, this will be limited to the Amazon App Store, because that's what it will be on Windows 11.
and while the Amazon App store has a lot of apps (most of the bigger ones, especially free to play stuff) there are many missing and you would need to buy paid apps again on that store in order to use them if you already own them on the Play Store.
KOTOR is also on the Amazon App Store btw. so, again, there is a bunch of interesting stuff on there
ALSO EMULATORS!!! of course we already have working emulators for basically everything on the Xbox, but it's not the easiest to get those running for most people, so having an android app to do that would be very convenient for normal users
edit: I just looked through the Amazon App Store, just to see what they got over there.
here some interesting titles that aren't available on modern consoles yet:
GTA3
KOTOR
Sonic 1, 2, CD (whitehead version)
Sonic 4 (meh I know)
Dragon Quest 1-8
Final Fantasy 3, 4 (3D remakes)
and yes, they have Retroarch!
