Hi ! I recently purchased Red Dead Redemption: Undead Nightmare Collection when it was on sale for 1000 MS points. Well at first i thought that i couldn't play it without the original RDR disc, so i checked it from internet. In this Part of a RDR Wiki: http://reddead.wikia.com/wiki/Undead_Nightmare#Undead_Nightmare_Collection It clearly says that i don't need the original RDR disc to play the UN-collection.. Well i then went and bought it, after i had downdoaded it i tried to play it just to notice a information box telling me to play the game i downloaded this for. So can i ask you guys working on Microsoft, are you trying to fool your customers or what ? I'd really like my money back or get this thing worked out some other way.
