Kid for some reason is asking for the following games. 1st three are found on Xbox 360, the Knight one I'll have to get on Series x/s.

Batman Arkham Asylum
Batman Arkham City
Batman Arkham Origins
Batman Arkham Knight

I know I can buy the Collection for Xbox x/s that has 3 of the 4 (minus Origins) but seeing what's out there.

There's some on eBay but wanted to check here first.

Located in Houston.

TIA
