It seems that I mistakenly thought that the backwards compatibility news of microsoft was a straight emulation , but it seems that is not correct . As of now there is truly not much to be excited about this . It seems it won't be a straight up simulation like the psx/psx2/gba/ds/dolphin emulators in PC where you can play anything you want . Instead it seems that each xbox360 game needs to have certain tweeks . So practically you insert the disc that proves that you own the game and download a digital copy that your XONE can play . The current list is laughable really , but it should get bigger with the passing of time .

It seems that they would also need third party approval for their games for this which doesn't seem unimportant and they are also making polls for users for which games they want to see ported first which is nice , but makes me want to facepalm when I see that in the top ten list of games xone users want to be ported there are 4 COD games

. While it seemed like a giant win at first for microsoft for me , with more info it seems that this could easily not be a big thing at all .
