Mouse aiming.
I started coding games when I was a small kid with access to Commodore 64.

I am trying to +1 this somehow. Know in your heart that I +1′d this.
I agree 5 million percent. :D
I’m making a game right now that uses 9 buttons, and that’s just for moving around.
Sounds like a complicated input scheme. A flight sim?
Close, a space building game which requires 6 degrees of movement and turning.
And then the consoles introduced Auto-aim.
…Which is still awful. Honestly I have no idea how console gamers play FPS games for fun.
I own both Xbox and PC and one day decided that I would get Modern Warfare(1) for the xbox. I had to take it back after 2 days and exchange it for the PC version because I found aiming so frustrating with a controller.
I don’t know, I can’t play any FPS without a mouse. But there’s some people who can play very well, especially the ones that didn’t play with a mouse and got used to the analog sticks from the beginning. Heck, I was playing Doom with the keyboard in the ’90s :)
Well said! ^^
