Basically just the title, I don't see an X|S category for this game, so assuming I would select X360 if I'm playing the Xbox Arcade version via Series X|S.

it doesn't matter very much, but i would choose xbone over 360 if you had to choose one.

we should either add the X|S series or simply have an XBLA selection in the pulldown that covers all xbox platforms.

Xbox Series X and Series S have been added to platforms.

Are there any visual tells a verifier could use to confirm that the correct variant of XBLA platform has been chosen?

I took a quick look on my Series X and there doesn't seem to be any visual differences that I could quickly spot.
