There’s a few that I can think of that almost fit the bill, but I believe you are correct.
We do have plans to develop stand-alone applications across all platforms (iOS/Android/etc.). We don’t have any plans for segmenting or breaking up the code base for distinct versions however. Each will function and play the exact same (minus UI tweaks), load the same mods, use the same save data, etc.
For the upcoming beta 2.0 release, the entire game is essentially being rebuilt. Our focus at this moment though is the Steam platform.
