Quoted from roc-noc:
Are these worth anything or just a white elephant?
They have a couple of things working against them value-wise. Like many old arcade video games, they're huge. Only sold locally. Imagine paying to have one shipped across the country. Secondly, there can't be a lot of parts available for them any more. Guys that are keeping them running are doing it for the hobby. No one is getting rich fixing Hercule's.
Quoted from Fatsquatch:
S L O W E S T and most boring game EVAR.
That's not the point. It's the biggest friggin pin ever made. By a mile. Like Orbitor 1 or Safe Cracker, if you see one at a show, you should play at least one game. One and done. Notch your belt and move on.
