Steam Version Query

Can i purchase the steam version and get all Season 1,2,3 characters even though I installed the PC Version from Microsoft Website, I would like to save my progress and would hate to start again via the Steam Client.

So if anyone could confirm this for me please.

MAny Thanks!

The Steam version has all the content available in the Xbox One and Windows 10 version of the game except for the extra colors you get from the Ultimate Source figures.
Also the game saves are not cross-compatible. You would be starting over from scratch on the Steam version.

Can i at least copy over the game files to skip the 45gb download?

To be honest I don’t know, but I sincerely doubt it.
