The "standard" version of the game Namco is selling is not the version that is in the picture in this thread. In my opinion the one being considered is a more desirable version.
The standard version is the version with the monitor inside an upright cabinet, like you see with Jurassic Park and HOD II. They really don't say anything about condition but I am sure they are not in perfect shape - they've been on location for 15 years. And, they are located in the Northeastern US, not California.
Like I said, $900 is not insane - this version of HOD comes up for sale around here sometimes and it's usually $900-$1100. Do people get that kind of money for it? I don't know. If it were me I'd offer less than $900.
FWIW, I could have bought a generic HOD cabinet for $100 a while back. Big mistake to have passed...
