Valve has 1/6th of that, develops games, and provides the entire worlds distribution of PC games. 1800+ is ridiculous, and clearly the wrong number, since they are laying off people.

Not in a long time. They're practically in maintenance mode with their games, DOTA 2 being the exception. Most of the creative talent there (people who worked on Half-Life, Portal, etc) has retired.
Valve is actually a good example of a company that's now incapable of doing anything really ambitious that has real demand. You know, like Half Life 3...
