Syberia is free atm on Gog.com. It's a 2002 3D adventure (third person, 3D characters with pre-rendered backgrounds) detective style with steampunk elements. Often gets on 'best adventure games ever' lists. If you like classic style adventures, although not point-and-click youmonkeyislandaddictbasts, you shouldn't miss this great one.
And btw, it doesn't have DRM nor needs some nasty client installed.

I can't get it right / Get it right / Since I met you...
