Dude...have you ever tried to use OpenGameArt or asset packs in anger? The quality is at best "uneven", you'll still have the exact same "but they're inconsistent" complaints, and then on top of that you get people whining that you used off-the-shelf art. (Rather like "oh it's an RPG Maker" game, which is something that Zeboyd Games, another low-budget indie developer, gets all the time; they don't use RPG Maker, but that's another story).

You can't make everybody happy. JV is going to more reliably make money by making his audience, like me, happy. Why should he change it?
