Personally I use my X-Box One the most right now, Fallout 4.
However, I play both PC & Console, so it depends upon which games I am focusing on at a given moment. When I am playing StarCraft, Civilization, or some of my classics I've picked up on Steam, I am playing on PC.
I am also not much for "brand loyalty" as it were, I've owned systems from all the major companies at one point or another; & I am old enough to remember being blown away by the original Super Mario Brothers on NES, because everyone was still playing on an Atari.
Yes, I am older than Donkey Kong, Mario, Samus, Link, & just about any other icon of gaming you can name.
