The game is a melting pot of ideas. If we were to blurt out the influences, we'd probably scream a list similar to this: Rygar, Resident Evil 4, Gears of War, Zelda, and Metroid. You've got your spinning disc thingy that cuts people up, your third person shooting style from RE4 and the cover system from GoW and you learn new skills and solve puzzles with said skills/items like in Zelda and Metroid.
What Games Radar said about the game graphically is pleasing -- it used to be fairly ugly, but they've complimented how it has turned out. Sure, it doesn't look the killer app for the PS3 and 360, but if your level of fun slows down after the holidays, this might just give you the shot of excitement you need.
