A lot of my favorite games are ones that people would consider "shame games". I see no problem with them.
I've got Barbie for the NES, and it was one of the first games I finished. Looking back, it's bad because of the gameplay, not the subject.
I collect Harvest Moon games. When I say I have over 20 different Harvest Moons, it's pretty hard to be embarrassed about other games, I guess.
