The holiest of NES holy grails arrives this week: Stadium Events by Human Entertainment and Bandai. This game is worth relatively little in its European release, and has almost zero value in its reissued "World Class Track Meet" version. But stumble across the original U.S. release and you've basically paid for your retirement. Special thanks to Steve Lin for allowing me to include actual photography of this rarity here. For contrast, the backup feature: Winter Games, a complete botch job of the PC sports classic by Epyx. It has no intrinsic value, either as a game or as a collector's item.
