Lithy,
Yes, they were both intended to be PLAYED and not neccessarily "collected". But keep in mind that home carts came in special enclosed cardboard/plastic boxes. That by DEFINITION means to be protected and displayed on a shelf. Not some paper box like nes games came in or whatever. Collecting video games is now a trend and is marketable; literally to the point that we now have two or more releases of the same game with different contents. Look at X-BOX Halo 2 for goodness sake...you can buy the normal one, and the special tin version or whatever. DVD box sets, again same shit. Hell even since the Atari 2600 days, in the game catalogs Atari advertized and sold molded plastic display cases to protoect and store your cartridges. (described as such in the ads)
Anything can be collected. Som yes, MVS carts are collected and building a complete collection of all complete MIB kits is very challenging and costly. But that was NEVER the intention of SNK. For god's sake, operators used to THROW AWAY old circuit boards once they stopped earning. Do you see laundromat operators saving and collecting there old washing machine circuit boards when they brake down or replace them? NOPE! But you know what, somewhere in the world, somebody collects those boards! But that in NO WAY means they were INTENDED to be! So again, ANYTHING can be collected, but not everything IS collected.
Please don't be "offended" by me or my comments though. I think we have met in person actually btw at the super auctions in Orlando. Do you remember? Anyhow, heck, I also "collect" MVS carts and I think they look great as well. But I just feel that it is a TOTALLY different market then HOME carts and should ALWAYS be treated as such. In short, the word "RARE" should be used far more sparingly and cautiously in the MVS cartridge "pool" then it is in the HOME cartridge pool. Do you understand my meaning? Nothing insulting, just an observation.
Lastly, with respect to your other comment, I NEVER said that the OPERATORS did the conversions. I clearly stated that the DISTRIBUTORS did them. It is possible that some smart operators did, but I know for a FACT that several distributors did. Do I have "PROOF", yes I do. But as I said, I don't want to embarass any of them who may be here or have ties to someone here primarily because a few of them are still in business today!
