PDZ is a superb game it has excellent graphics that look so superb you wont have worry about forking out 1500quid to get a HDTV. In which cases is a good thing. Its very easy to get into and was the first real 360 game i ever played (apart from COD2(i played it in shops)) and i tookl me around 12 minutes to get the hang of it.
Although the audio can sometimes sound a bit goofy its still really good and you wont care, the voice acting is great im just saying the death match audio is sort of crap. I recommend you buy the normal version of the game as the collecters edition does host loads of extras but you wont really get round to taking a look at them. I have the collectors edition but i dont really care get whicever you want.
I havent played much of this game as of yet but i heard its quite short, but once you complete it you can just mess around on Xbox Live or just play deathmatch etc. by yourself or with some mates.
PDZ is a game that all 360 owners must have in their collection because at the moment its probably (going by everyone else) the best 360 shoot em up so far.
