I have a portrait-mode monitor. And a landscape-mode monitor. I'm fine with putting games on the landscape one but you've got to let me do it. My visible desktop area makes an L shape.
Even on the landscape monitor, I don't want games to run full screen. I'm probably streaming and that involves other windows that have to be visible somewhere.
My keyboard layout is Dvorak.
I have a very comfortable ergonomic keyboard that I prefer to use. Its arrow keys are split across two hands.
I didn't play shooters in the '90s, I played ZSNES. My directional controls are ESDF (or, more literally, .OEU). I find WASD to be weird and cramped and there's not even a nub for my index finger.
If you ask me to use the controller, or design a game that really wants the controller, that's fine, except if you tell me to press "A" because you mean "the face button on the bottom", I'm going to press the face button on the right, which you probably call "B". I know I'm factually wrong about the button names on a PC, but I grew up playing Nintendo games and you cannot change my muscle memory.
Sometimes I accidentally leave Joy2Key running.
It almost sounds like I'm intentionally trying to be difficult, but these are just the circumstances of how I use a PC, which is also the place where I play games. And I manage to play a lot of games. As long as they have a spectacular options menu. Which I know is the hardest part of a game.
Last year I tried judging indie games for MagFest, and I realized that I should probably not do it again, because my experience trying a newly-developed game has nothing in common with anyone else's.
