I know this is a huge issue for most gamers as well as myself so I would also like to tell you that we won't be using DRM for Divinity II.
No DRM = no disc check and no Internet check, if you ask me...
We will be using a disc based security similar to Fallout 3.
The disc being needed = still DRM. Very, very mild, which is good.

I'm glad there will be none of those Securom Internet Edition DRM Checks with install limit crap going on -- like many of EA's games had before (Dead Space; Mercenaries 2; Burnout: Paradise; Mirror's Edge; and etc etc.) and that also Sacred 2: Fallen Angel had going on.
So, since you said it will be disc-based check -- will it be the (old-style) Securom disc-based check? Tages? Or you going with someone else here? Or are you not allowed to say?
