As someone who started console only and eventually got into PC gaming it's not always that simple. Half the time you don't know what exists until you stumble across it or have it suggested to you. I got into PC for the better performance, but over the first year I found that I really enjoyed a whole bunch of game types I'd never really glance at before since I didn't have the hardware. Steam for instance did a great job of introducing me to new games before it became completely buried in content like it is now.
