Half-Life 2 Episode 2 Concept Art - Citadel

It as been 6 years to the day since Half-Life 2 Episode 2 was released - with no sign of Half-Life 3 for miles. In those 6 years, we have seen the release of the entire Mass Effect series, 6-going-on-8 Assassin’s Creed games, and 6-going-on-7 Call of Duty games. 

Also, G.W. Bush was still in office and the subprime mortgage crisis wasn’t a thing yet.
