I recently have been snapping off on my Vic 20 collection(over 70 carts,40 more label Variants, and including Princess and Frog and a Xenox double ender of Artillary Duel and Chuck Norris. I got a decent collection, and I recently scored some rare games sealed. In the lot, I got Snakman(a pac man clone on tape, complete and in original packaging. It is made by Microdigital copyright 1981. Is it butt common or is it rare? I love wierd old computer games, I know that I will have an answer here!
