Since EndSpace I've wanted to try a game that uses real planes, like F-16 or F-22 or something. Overflight gets pretty close: it's a multiplayer only WW2-era dogfighting "sim". Only one map, and the map is pretty bland, no upgrades or customization, no single player missions (although bots are available). But it's in a cockpit and you can look around.
I've been waiting for something like this, and... I played it for about 20 minutes tonight in total, including a short break. That's literally all I could take without throwing up. I'm not especially sensitive to motion sickness (I feel it just a little in EndSpace and Omega Agent) but this game really hits me, especially if you have to circle more than once to find your target. It's not as bad as the GearVR roller coasters, but it gets close sometimes.
I'll keep trying it. I can see how it might appeal to some, I definitely haven't fully explored the game. If you have a really strong VR stomach, it might be a lot of fun.
