drm is something i've just grown to accept. having my games in one place, stored in cloud easily overweights drm for me anyway.
I like that too. That's why I have GOG. 
Plus I can play Prison Architect while my kids play Red Faction at the same time. 
gog definitely wins the compatibility + overall quality competition. in terms of quantity + support + seamless updates however, steam is the king of the hill.
almost traded mad max for prison architect a couple of months ago (traded for evil within instead
). introversion has been one of the rising stars at the advent of the whole indie scene, so it must be interesting at least.
damn red faction, i have yet to finish that too. recommend the pure faction community patch.
