iippo: Hang me by balls if thats what the drm-free fever necessaties you to do, but do definitely understand why the early access in steam only.
Oh, I think most people do - Steam's patching is well-suited to this - and I would wager that a lot of people who prefer DRM-free are more conservative in their tastes, which means they would not really go for Early Access either.
The problem is that a lot of Early Access projects seem to have vastly overestimated the potential number of early adopters. Godus, for one, doesn't seem to have taken off at all, taking in just $100K from sales despite what must be its 7th or 8th sale now, and that's actually a more prominent Early Access title.
Obviously Starbound is one of the more successful ones, but I suspect the devs put the DRM-free mark there to get DRM-free gamers on board in anticipation of difficulties. Starbound had the benefit of a lot of positive media coverage beforehand.
For my part, I do think the game looks interesting, but I'll be waiting until it's complete so I can enjoy it to its fullness and be sure that a DRM-free version is actually coming out (not that the dev suddenly does an about-face and decides it suddenly wants to use the Steamworks API only).
