Just a quick question and maybe someone can help me out. I recently bought a game on eBay. Game I bought was Caltron 6 in 1 for NES. I was reading some info about it but I must have read it wrong. I THOUGHT there was only 888 of these made w/ a serial # on it saying which one of the 888 it was. BUT come to find it that was only with Myriad's 6 in 1, not Caltron. Is there some type of site that gives out an estimated production # for rare games? Thank you!
