I was looking at the destiny limited edition on the gamestop website and when i scrolled down to read the Important info, the fine print said:" 20GB HDD Xbox 360 consoles cannot play Destiny without a hard drive upgrade." this worries me because even though i'm using a slim, i'm also using the hard drive from my 20 gig 360 from way back. Does anyone know any more of this? I don't want to make the purchase only to find out i can't play because this. Also if you read this and know anyone with the same situation as me let them know...
