Is the Steam version DRM-free?

[DIGI Byte]

As the title says, is it DRM-free?

DRM-free, in a sense that it actually doesn't require the Steam client to run properly.

I don't understand the reason for this question at all. If you don't want to use steam why not just get the normal version of the game and avoid this "steam" thing (whatever it is) altogether?

I think he wants to make a copy/paste version, since games from steam don't register in the registry, its most likely he wants to copy it and give it to his friends without giving them his steam log in details

there's no other logical reason why he would ask that
