hedwards: You do realize that Steam doesn't require DRM use, right? Most of the time Steam games use the DRM, but it's not something that Valve forces as far as I know.
Yes. But so far the KC:D devs have specifically said that they'll be using Steam's DRM, although they'd like to release KC:D here (although releasing it here would not help with regards to having a DRM-free version for Linux...).
We get many questions about DRM and whether our game is going to be DRM free. Frankly, we have to admit we are not sure at this moment. We are planning to use Steam on open platforms, so the game will be using Steam default copy protection mechanics. Other options including GOG.com are being considered but can't be confirmed as of yet.
When I asked them about a DRM-free release (and even pointed out that the game can still be DRM-free on Steam & that would be a good compromise for some of us), they told me that the decision is entirely dependent on their main investor and retail distributors:
The main PC platform will be Steam but yes, we'd like to publish it on more sites, GOG.com included however we cannot confirm it yet. Stay tuned for more info in the updates.
The problem is the fact that our investor and/or distributor will probably have their own opinion. We will try to bring you a really DRM-free version but we might not be able to. At least not on the launch day. And we think that Steam default copy protection (meaning that you need Steam running, but it can be in offline mode) is a good compromise.
