On what platform do you guys game

Primarily on PC. I've come to find that almost all games are just plain better when run on PC. For example, you can use a PS4 or XBox controller on PC if you prefer that for a certain game (like Mortal Kombat or other fighting games). In fact, most consoles these days are just essentially PCs with a preinstalled OS.

The only exception I see to this is probably Nintendo Switch games.
