Well my main contention isn't whether or not it would "work" due to Microsoft's or Valve's intervention . I am just curious if the games would actually function correctly or if there'd be a ton of caveats. I mean, a PC owner can buy a Steam game and still end up in a situation where they need to patch it or otherwise do some extra stuff to get it running on their system. Can we expect the XsX to fare any better? Seems like the sort of promise that looks really good during marketing and trade shows but ends up being a complete circus when it comes to implementation.
