Still very confused. Just now a game designer friend posted on FB about submitting her new game on here. Thing is, like mine it's still in prototype form. I asked her how this was possible and she replied 'My understanding is that if it's 100% definitely going to be published, it should be in the database.
I think everything on KS should have a BGG database entry (and most things do)'.
EDIT: Aaah, maybe it's being Kickstarted. Will check with my friend.
BGG doesn't have perfect consistency. Frankly there are a number of games in the database which have nebulous provenance.
