I don't even know what DRM is ._. but if you want to share the game with friends. buy them a copy ^_^ more love for Larian since they have shown us all love.
(still those long hairstyles~ my sister and I forever love Larian!!!)
That's not sharing.
Mostly, when a friend asks to borrow or copy a game, they end up buying a copy for themselves. I do motivate them to buy a copy, but I have no problem giving them a copy for them to try it out.
