So, I got to start up Eagle Flight tonight -- couldn't find any online matches ... servers may not be up yet, but I did fly around the tutorial and complete the prologue.
I have to say, the flight was super smooth in the game -- no nausea or weirdness while flying. There was a bit of a rush as you scrape by a roof or something, like in a lot of VR games, it can sometimes feel like you're right there. Just flying around was really serene and peaceful -- and a lot of fun.
I can't wait to explore some more, but I think I'm going to wait until my Pro arrives. Although, I may try to get into an online match tomorrow, at least. Anyway, if flight is something that interests you, from what I'm seen so far, this is really fantastic. I can't speak to the depth of the experience or how the multiplayer is, but it's so smooth and easy to do -- I can totally see this being something to show new people.
Oh -- controls. You tilt your head to turn, look up and down to, well, go up and down. L2 slows you for tight turns, and R2 speeds you up -- but it's mostly done just by looking.
