Ciris: Guys, we've been in contact with the developer for a while now in order to get a build fully free of DRM (not even with a universal CD-Key).
We're hoping to get that ASAP, but the solution in the meantime is to play the game offline if you DO want to play it while it has DRM (so as not to NOT be able to access it entirely).
The build with no DRM is on the way - and I'll inform you in this thread when it does arrive for those that would like to hold off on their purchase until that happens.
I think the thing a lot of people are now wondering is, why did you accept this in the first place? Did you know about the DRM and accepted it anyway or did you not realise (in which case surely the developer is in breach of contract)? Either way, the game should not be on sale in its present form. You have failed us on your one remaining principle, the one you dropped others to further pursue. The game should not have been sold in this form.
EDIT: If you've been in contact with the developer for some time and they're still not holding up their end of the bargain, I hope your contract with them has some kind of clause that actually requires them to provide a DRM-free build.
You might need to actually apply some pressure because it kind of seems like they're taking the piss at the moment, making the game DRM-free in single player should be pretty trivial for someone with source code access. It comes across like they're just not that bothered. Not being DRM-free, the game shouldn't be sold at the moment and there should really be a deadline for them to provide a DRM-free version by. Perhaps the threat of the game being removed and customers refunded (from their pocket, not just yours) would motivate them.
By the way, I have asked for a refund in my reply to that ridiculously poor support response but have yet to hear back. Given that the game was sold under false pretences, I expect this to be sorted sooner rather than later. The solutions of 'put up with it' or 'wait' are not acceptable to me. The game was sold to me as DRM-free and it isn't.
