The camera sucks, really, really badly.
I haven't had that much trouble with the camera. It's not perfect though. There are times I'll want to change the angle with the right analog stick, and if I let go, it'll slip back to the default view.
There are only sixteen Colossi in the game, and those are the only enemies. But damn are they fun enemies! Half the fight is figuring out how to get to their weakpoints. It's not just a case of climbing up their leg and stabbing at them. You really have to pay attention to the environment.
That said, there are no minor enemies. This is not a hack and slash fest, nor a dungeon crawler. The world may be "empty" as far as enemies go, but it's so full of life! Deserts, forests, lakes, canyons.. It was really masterfully crafted. That said, this game is probably a generation too early. I cream my pants thinking about what this game could've been like on the PS3.
And there IS more to it than fighting the Colossi. After beating the game, you'll unlock a harder mode of play (which REALLY changes up the way you'll fight some of these beasts, as new vital points are added in a lot of them), and a time attack for both modes. Beating the Colossi in a certain amount of time will net you special items, like new weapons, masks, cloaks, and so on.
While it's a bit light on the content, it's chock full of style. The presentation is gorgeous, and the open-ended story is very refreshing. I can't say I was completely satisfied with the ending, but I've seen a whole lot worse. Word has it the team that made this is already hard at work on a project for the PS3. I can't wait to see what incredible world these talented folk will whisk us away to next!
