It took me a couple days to acclimatize to the Rift, but I have to agree it's a great experience. I happen to have a full HOTAS setup, pedals, and voice attack so it ends up being a really great experience. I actually played quite a bit in the Eagle and then upgraded to the Viper - and it totally changed the game. Suddenly, I went from a very cramped cockpit to a spacious interior. Even though my actual room hadn't changed, I felt like I was in a far more comfortable environment. It was crazy.
I actually find that docking and dogfighting are quite easy even at the DK2's resolution. The 3D effect really makes it a cinch to judge distance when making more delicate maneuvers. Menus are a bit harder but changing the HUD color was clutch.
