God I love CD Projekt. They're the best developer out there in my opinion. They don't have any DRM, create great games, and are lovers of video games just like we are. When they release a new version of an existing game (e.g. Witcher Enhanced Edition), owner's of the original get their copy upgraded for free.
Also, if any of you weren't aware, they run Good Old Games (gog.com). All games are DRM free, brings back classics and makes them compatible with modern day computers, and they'll soon be releasing a client like Steam for our libraries. I like to support these guys whenever I can.
(Sorry if I'm super fanboying over here)
