- why not, some people have preferences and turnoffs. Granted the particular type of debauchery could be described in annotation. And frankly i personally rarely look at other tags, so if i see incest tag i will just open said game page and read about that particular game/look at screens.Just to play devils advocate here; should we also have tags for aunt, uncle, grandmother, grandfather, cousin, etc? I think incest tag is nice and rounded, just my two cents.
