DO NOT SELL THIS STUFF!!
You will regret it forever. This thread makes me upset. Seriously DO NOT SELL IT if you love this stuff that much.
If you have no emotional attachment like the eBay clowns its easy to part with. You seem to have trouble dealing with the possibility of selling it which means you SHOULD NOT get rid of it.
As a huge Sega fan also just don't do it. It's almost criminal - I feel like I'm watching someone give up their first born child or something. Painful.
