Played it on console, mildly interesting. It is very linear, combat sucks, can be frustrating at times and verrrryyy bland environment with every shade of brown and gray you could hope for. Don't know what differences there are between Xbox and PC, but I doubt it's much.
If I was your friend I'd point to towards a J RPG before I'd recommend this, but I'm not so feel free to give it a try.
-Edit- Oh, and I think it qualifies as "action adventure", that should be all you need to know
