Play Lair on PSP
You actually can play Lair on your PSP. Connect your PSP via Remote Play, click and the Lair disc (assuming it's in your PS3), and get going! Unfortunately, there are multiple restrictions including the non-functioning of the PSP's L and R buttons, meaning you can't lock onto enemies, slow down when flying, hover or land. Also, you don't have to use Sixaxis to control your dragon anymore. Instead, you can use the PSP's analog stick. However, the entire game (except the tutorial) is technically beatable on your PSP.
