If by DRM you mean the game won't boot up without an internet connection check, then no, most games do not require the internet to run. Even GTAV loads up fine in offline mode. As it should.
Even Ubisoft's Uplay and Origin clients have offline modes.
Games which require the internet to load up, even though they have single player modes, deserve a thumbs down. Steam has an offline mode, and game publishers should respect that.
