Valve is no longer in the business of making games, but they will make a game to help market and sell the Valve Index, and that is what they have done with Half-Life: Alyx.

Half-Life is probably Valve’s most famous gaming title, so they are starting with a Half-Life VR game. Portal seems like a natural fit for VR, so a Portal VR game should not be far behind. They should just create a new Orange Box VR bundle with Half-Life, Portal etc.
