Known Issues Ruin XBox Live Old Originals.
Seriously, why pay $15 (1200 MS Points) for a digital download that you do not physically own, when you can get most of the games used for 5 bucks (or brand new for 10 bucks like Fusion Frenzy and Fables at Circuit City). Not to mention with the actual disc, you can play it on both your 360 or glitch free (gasp!) on your original Xbox, as well as take the game to your friend's house and play it over there.
