Differences between free and paid version:
Free – New version of the game is released after some time when more stuff is done. Hotfixes are released when they are done. You must download each version separatly.
Paid – New version, patches, hotfixes, features,… are released without any delay when they are done. You just download launcher and every patch is downloaded automaticly. Most important – your karma will rise up;)
