Perhaps you could mention over half these variations of farming titles--true to some degree except Abzu, which similarly has no DLC--are only the core game, meaning they can shell out only a max up to $45.50 USD for most the extras while they are STILL CURRENTLY ON SALE ON STEAM, discluding the normally $8 Supporter Pack for Crab God (10% barely qualifies).
Anyway, dastardly sneaky move on Humble and the publishers part, why I always check games out beforehand, also why I'll short both on custom if I do. You should too. Better for the charities anyway. It's not like they're not getting more from people who buy the DLC. Blasted grifters.
