Do you guys have this feeling too,i mean i can't find some uncommon games,but found some rodlands

exsample's
bucky o'hare- great game that i played as a kid(rental) only 1 time i saw it,cart only bought it lucky me,but never saw it again,ever
bigfoot,never saw this game in the wild
boatduel,this game is more rare here than rodland,never saw this game,in wild or on the net.
Maybe im looking at the wrong place

ALSO some medium rare games are more rare than the A+ rare games like rodland and mr gimmick because the get less attention.
I mean these games you can find on ebay but rare games that are not that common,don't see them
-snowboard challenge-this game is a real b*tch too find ,and a game thats in the way of completing my pal collection
-panic restaurant - trolls in crazyland - mighty final fight
what do you think,also had these kind of problems
