I think it's more wanting to play games to a better standard. I've always been fine with games graphics from a technical level but when it comes to presentation through resolution I'm immensely picky - I've bought many PS3 to PS4 Remasters purely on the 720p to 1080p upgrade and I can clearly see the difference. One of the reasons I bought the 360 was due to this, so instead of buying titles on the PS2 if there was a 360 version available I'd get them - Just Cause, Gun, Disney's Cars, Bully, Burnout: Revenge etc.
Also seeing these Xbox One Enhanced BC titles... they really do look impressive - Final Fantasy XIII looks like how I'd imagine a PS4 Remaster to be and that's using the original disc!
