Actually, Securom has been removed from DKS. You can download the update from the link below for any non-Steam version of the game (it is available directly through Steam for that version; not sure if other digital distributors have also released it themselves as an update).

Dragon Knight Saga DRM free patch


Nothing has been mentioned about copy protection in Dragon Commander, but Lar has said in the forum and his blog that he is not a big fan of DRM. Larian removed the DRM from Divine Divinity, Beyond Divinity and DKS (contractual restrictions prevented them from removing it from the original release of D2:ED).

Larian is self publishing Dragon Commander, so hopefully that and the success of DKS will make it easier to get a distributor in the US/UK than it was a publisher for Divinity 2.
