Inspired by Smrifnack's low-risk, open-ended offer to trade, here's one of my own:
I have extra copies of Dungeon Explorer and Super Star Soldier--no cases, boxes or sleeves, just games and manuals.
The DE manual shows some wear and has marker on the back but is in one nice, solid piece. The Star Soldier manual is wavy from water damage.
I'm looking to trade them for any PC Engine games I don't have (which are only a couple dozen) not released in the U.S. Common CDs or loose hucards are fine. I'm mostly interested in getting games that are fun to play (like SSS and DE) and don't require reading.
I've bought from or sold to:
hindsr1976
Michael Helgeson
Neokellyzero
merriman_bk
rolins
Nemo
D-lite
Sinistron
SNKNostalgia
Old Rover
Estaban
and have 100% feedback as "vestcoat" on ebay.
