Quoted from arcademojo:
Well the LE listed in th market place is #71 so could we say at least 71 LE's were made. My guess would be about 150.
I actually made a topic about a year ago asking about LE numbers and the amount they made of the game Scott. I personally have #234 (bought from Art/Oldpinguy) and on ipdb the LE on there is #343. The consensus on the topic was the plates are randomly placed but if they're not there would be at least 343.
As for the LE itself it's broke. Stern needs to fix the code for it to be fully playable unfortunately. It can be a pretty fast game which is cool but if I wasn't such a big wrestling fan I wouldn't own it.
