Hi I downloaded Civ Rev but can't play it on other gamertags only the one which d'loaded it. My family won't be aible to play it, only way is to buy the disc. How bloody stupid is that? Microsoft always bang on about getting the family to play together but how can they when the resorces are limited? One gamertag per xbox can only play the d'l.. ridiculous. It used to be any gamertag registered on home console can play the content, and now microsoft are gonna kill the 2nd hand market no wonder they're hated. Look at Win8 for instance they get rid of the start menu and button.. in future ask your followers what they wantt because you can get a program that will get the start button back onto Win8. My rant is don't alienate your core audience otherwise you can forget about people buying xbox720.
