Well it plays all ways. PC misses out on the console exclusives, consoles miss out on the PC exclusives, consoles themselves have different exclusives and don't interop. For people getting into gaming when they're young, a big influence is probably what their friend group is playing on, which in turn is probably inspired by whatever their parents decide to let them on. That or whatever games is latest hotness.
When I was young Minecraft forcefully evangelized my friend group, which had previously been more nintendo/xbox, into PC gamers. The origins of a lot of my current interests and career go back to the initial questions of: Why is minecraft running at low FPS? How do I set up a minecraft server? It's a little different nowadays, when some of the biggest multiplayer titles are cross-platform.
