sell em at e-bay if u want, if you still want a copy u can *whispers* burn it, well a copy for yourself. i dont' mind burnin games, well at least ones that makes millions of dollars because super diablo is popular.
i would sell em at local, gaming store, we have some around here, but they don't give much at all. For my x-box nba 2k2 they only said 6 bucks!!! i mean thats crazy, so i just kept it. try e-bay, but i bet you wouldn't get crazy amounts.
