What is the difference between the Xbox one and Xbox 360 versions of all the infinity games

Not much in terms of graphics (yes the Xbox one version is better looking but not by a lot tbh).

You can build bigger toy boxes. The differences aren't great though.

Also, there is no 1.0 for Xbox One. So you'll miss out on all 1.0 playsets. Still mad about that, it's like Disney, I want to give you more money but you won't let me....

Maybe it will get the backwards compatibility treatment for the Xbox one. Stranger things have happened...

I think the backwards part doesn't work well with accessories but would love them to do it or just re-release them on the new consoles

Microsoft outright said any games that need accessories, be it Kinect or a base of any kind, are not fit for Backwards Compatibility.
