It's almost embarrassingly small compared to some of the other collections I've seen yous guys own here. I hope no-one laughs.
First one here is pretty much just what I pulled out of the closet a couple of weeks ago. Most all of it I bought brand new in 1999-2000. I do see one rumble pack with a torn bar code label on it, so that must've been used.
I stopped buying DC games when I bought a Gamecube on it's launch day later in the year (I missed Metroid badly back then), so it was pretty limited to the 12 you see here. Kicking myself now for not spending $100 bucks on them in 2002-03 when they went on clearance.
This is what I picked up at a small retro games store last weekend, after I hooked my DC back up. I got these along with an SNES Killer Instinct and Genesis Arch Rivals CIB and cart only of Roadblasters.
