If you actually wish to try playing one of these obscure games, you can check the usual places. I refer of course to eBay and Amazon. Not very many of these games are especially rare (though there is the occasional rarity such as I.M. Meen) and many are readily available for quite cheap on eBay, often from sellers who have plenty of discount games (since that’s where I got the games in the first place).
Don’t bother asking me to send you any games. I will just direct you to the eBay and Amazon.
