I mean, you had my money there, the others are kind of a bonus.
Really hope we will see further support from these companies in particular with BC. They all have games right now that are unavailable and highly requested (Tales of Vesperia, Binary Domain & Vanquish, a bunch from Capcom, and KoFXIII) and adding them to the service along with MS's own first party 360 games (Blue Dragon, Lost Odyssey, Crackdown 1&2, Fable series, etc.) would make the price an absolute steal for last gen games alone.
And MS, if you get OG Xbox games included in this?
And get the 360 emulator up and running on W10?
And package all these services (Game Pass, EA Access, XBL Gold) together with every Scorpio purchase?
Might get a stew going.
