Right. Digital distribution.
Though PCs have, for a LONG time, had the superior technology and number of games. For many it was an ease-of-use issue, because running PC games with the proper technology requirements was much more difficult than popping in a console game, knowing the requirements were built in. Steam and similar services make it easier to buy and run everything, and consoles are more and more like PCs now with their options, so there's less demand for the relative historic simplicity of consoles.
Probably 75% of my gaming, lifetime, has been on the PC. In any era, even when it lagged behind in sales, you could make a case that it was the best platform for gaming. Good to see the pendulum swinging back its way again.
