Fully expecting flightsims to make a glorious comeback with Oculus' full availability. It is too well suited to games which require you to sit still, and have your hands on controls.
Unfortunately, the Oculus has some issues with full flight sims. It's still extremely neat tech, but I don't think I'll be giving up head tracking for it any time soon.
First, there's the resolution issue. I've only used DK2, but its resolution was so low that I was unable to read the dials/HUD without getting my face super close to them, which presents major issues when trying to maintain situational awareness.
Second, no matter how many buttons and switches you have on your HOTAS, you're going to have to manipulate something with your keyboard/mouse at some point. This causes some obvious problems when you have an Oculus strapped to your head.
Time to buy shares in joystick manufacturers.
