Firstly, i'd just like to say sorry if this has been posted before, I wouldn't be surprised if somebody else has ranted on about this. Why don't xbox live allow us to preview what we're buying? I mean i've look ALL over the internet to find this one god damn gamerpicture (http://oi45.tinypic.com/bev4h4.jpg) and I finally narrowed it down to the game Halo 3. However, there's so many pictures packs and I can't preview them? How the hell am I supposed to know which one is which?! If somebody could help me i'd be very grateful.
EDIT: I know most of the new games allow this but still not the old games! :/
