Nice find, I completely forgot. I remember either me or a friend having the XBLA disc, but I never even connected my original XB to the net, so I never used it, I just played offline.
Great console btw, funnily it was the one that turned me from PC to consoles, so I could play the newest Mortal Kombat with friends. I since switched mostly to Playstation, but always had some kind of XB from every gen.
It really hurts to see how MS dropped the ball with the console since, after doing the impossible and narrowly outselling Sony with the 360. I really though GamePass might turn the tide in their favor again, but as Sony now has a similar service, it seems to have not.
