A gamer has been lucky enough to receive the final retail version of Lair and he shares his hands on impressions with new screens and much more. You can ask him questions right now as he is willing to kindly answer any questions people anticipating Lair have.
"All Questions I have answered put together, Including the ones from the GameFaq topic I made for this:
1: What dragons have you unlocked?
Well, for every mission you earn medals. Since I am just trying to beat the game, I am not getting the best medals yet. I think Gold Medals are required to unlock other dragons.
2: Is the game really only 6-8 Hours?
I bet if you were an uber pro and you could beat each mission on your first try, and get a gold medal on each one on the first try, it would be possible to beat in 6-8 hours.
But, for normal people like you and me, It would probably take 12-16 hours just to finish the storyline, and then you have to get all the gold medals, which may take a long time.
