I suppose then that'd be the difference between a company/developer like Bungie submitting a 'first chapter' or introduction vs. yourself or an indie dev. Other games have gotten away with worse, including indie games. It's not excusable just because it's Bungie, with that in mind, they still have my attention. Edit: If they did indeed lose much of their initial lore because of a writer taking much of his intellectual property with him it's no surprise the game is fairly barebones.
