Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - General @ Larian, Steam Activation for Boxed Version ?

The Boxed Versions are on sale in some german Shops. On the packaging is written " Steam Activation needed".

FAQ for DOS says, there is no DRM for the Boxed Version. It seems, that this is not true.

Does that mean, that the DOS Boxed Version can not start before 30.06.-Steam Date ?

Thx for yoyur Answer!
