All I know is i went into appdata, found a codex folder and all that sort of stuff, tried to clear it out, and then bought the game on steam, loaded it up, and my saves and everything were still present.
In any case, I've read somewhere that the non-Steam version actually saves stuff in your registry if you sell your soul.
Originally posted by Nixitur:Wait, so, the game does stuff in the Steam folders even though the copy you had wasn't a Steam one? That's.
