Valve released Dota 2, and then ported it to a brand new engine, they've been consistently adding updates to that game for 10 years, they've been working on CS:GO, with similar effect, I think you lot forget that the majority of Valves developers were working primarily on team-fortress and counter-strike as mods before they hired them, they're primarily a multiplayer house.

Valve unlike most companies maintains their games for more than 10 years.

Just because they haven't released anything obvious to the casual observer like new single player titles that is easily marketed is only showing your ignorance of Valves entire catalog of games, and attitude to development.
