Steam forces their own DRM, Steamworks, on all games.
Nope.
I know of at least World of Goo, Prison Architect and GTAIV (which has it's own DRM) in my library that will play no problem without Steam even running. I probably have more, but those I've specifically tested.
GTAIV was particularly useful, because Steam forgot I even owned it for a couple of days at one point soon after I bought it - I couldn't play it from within Steam, but I could play it directly, with Steam closed.
