What I find interesting is that I'm starting to see PCE Works games show up on Yahoo! Japan Auctions, and they are attracting a lot of bids. Space Fantasy Zone copies are consistently going for over 25,000 yen, and there is a copy of Super Real Mahjong Pantsu edition that is at 31,000 yen right now.
I used to think that Japan was immune to bootlegs, but it looks like that is not the case.
