I've never seen that game before, but it looks VERY unique (in a good way).
It must be more collectible than something more average.
Nope.
The arcade hobby is mostly the opposite of other collectible hobbies where scarcity = higher price.
The big factor in arcade machine pricing is demand, and the more fun the game was, the more demand there is for it. So ironically, because those games were more fun, there were more of them made. So what ends up happening is the "rare" stuff that wasn't fun doesn't have demand, and won't command much of a price.
That's the general rule, with some exceptions.
