Considering how a lot of Working Designs games have been climbing up in price over the last few years, I'm actually surprised that Cosmic Fantasy 2 is as reasonable as it is. Much better than the prices on their Sega CD and Saturn games.
There's nothing surprising about it. It's probably the most overproduced TG16 game. The market's been flooded with 'em for decades.
That explanation is based on logic, and logic has no place in a Retro Game Collector's life.
I've always been puzzled by the low price of this game. You'd think people would be gouging the shit out of each other for it. The US library is pretty meager, and IMO this rates as a very important game, TG-16-wise.
