There is no value in pirating games for Xbox... I mean you can't play them online because you'll get banned.
Question is, why pirate when you aren't getting full value for the game. Sure, you may get away with it for a few months but as soon as they release a kernel update like they do twice a year, then say bye-bye to your console.
This is what developers/publishers have been doing for the past 18 months. Releasing down-loadable content that you can only get when you buy a game legally and unused and it has worked pretty well so far.
Slightly different for the PS3 now though.
Ps: about the xbox scene and any other scene i just like to keep myself informed.
