The problem is that it's a nice multi-player brawler that most people enjoy keeping in their gaming library. With eBay steadily fetching $200-250 for the past year and a half, there becomes no incentive to sell it for drastically less locally. Any time I've seen one of these come up on KLOV, it's gone within a couple of days unless the price is in the upper range, and even then it disappears eventually. The game does not seem deserving of this price, but there are always more people looking to purchase it than sell.
Due to the value it commands I've thought about selling mine, but it's just such a fun beat-em-up that I haven't been able to do it.
