It's something different and I like it.
The game is fun. Just plain fun to play. The motion controls at first took me by surprise because they're much more sensitive than the motion controls used in Heavenly Sword. But once adjusted to the game plays very well. I don't see how the controls are "broken" because they work perfectly fine. If you like them or not is a matter of opinion but saying they are broken is another. Like I said, they work fine but it may take a while to get used to such as doing the 180 turn the first time can be a pain but now i can pull it off nearly every time. (I managed to do it on my first shot somehow). The controls feel right and when you get into it, you sometimes forget you're tilting the controller.
The lock on system works fine for me as well though I hardly use it as I tend to just manually aim as it still gets the dragons you want. It's not much of a problem though the camera can sometimes be a nuisance when when you kill a locked on target.
The graphics are awesome though the ground textures seem to be a bit weak as they don't seem very sharp and very clear though this can be easily overlooked as you tend to be flying at high speeds or burning infantry on the ground. Everything else though looks great. From the dragons to the water (doesn't look like sand), to the buildings and fire. There are a few popups and slight frame drops though they're nothing as serious as you would find when playing TES: IV Oblivion.
The sound as well is amazing and quite memorable. It really sets the mood and atmosphere of the game and can really immerse you into the game. I've still yet to hear it in surround sound but even so, the sound track is amazing, adding to the suspense and urgency of the missions.
The only problem I have with the game is that it is too short but this seems to be the case with most game nowadays though there is some replay value as you'd want to go back and redo missions that were just awesome to play through the first time. Not only this but you can redo them and try and get more medals or just try to beat your personal best on carnage or time etc. If your skeptical about this game, rent it first before you go out and buy it. Lair is an amazing game and is worth having if you own a PS3, just don't get it if you hate motion controls and want to switch to analog as there's no option.
