Lair looked pretty cool, but then everything in the gameplay movie I saw was very repetitive.
Fly around, shoot fireballs from a dragon's mouth that sounds like a cannon(even seems like it's autoaim, not sure), land on the ground and kill a bunch of NPC soldiers that look like they probably don't even harm you, and fly back up in the air. Rinse, repeat.
There's a ton of action happening at once though. That was cool. FPS gets pretty bad at times though when you're on the ground and the dragon is breathing fire everywhere.
