It's a bit tight with glasses, but it's okay, you get used to it and it doesn't hurt.
As for Eve: Valkyrie, I must say that game looks amazing in VR ( which is pretty funny because it looks pretty average on your screen due to low-res textures/geometry ). It runs really smoothly too despite me being under the minimum specs ( Radeon 7970 ) and I didn't feel any motion sickness in the hour I played, but I might be a particular case since I'm used to playing 360° in space, hehe. The "maps" are pretty small and repetitive, they're made of ships/structures, wreckage and asteroids with pretty planet backgrounds and nebulae, but it doesn't feel like there's much content. Solo seems very limited to tutorial missions ( which are nice but very short ), some free flight and surviving NPC waves. Not exactly very deep. The meat is in the multiplayer; I tried team deathmatch and had a blast, with some good action and fancy special effects. It looked a bit repetitive though, so I'm not sure the game is worth $60 on its own. Immersion in VR is impressive, one of the best and most comfortable experiences I've had.
