Valve: Feeding Us From Under the Table

Valve created one of the most immersible games of all time with Half-Life 2. They ended it on a cliff hanger. The next game Valve made was the follow up to the cliff hanger ending, Episode 1. A bit more than a year later, Episode 2 landed, ending in a larger cliff hanger than the original game. And now what is Valve doing?

Everything but creating Episode 3.
