Remember Electronic Arts defending lootboxes because it claimed they brought "a sense of pride and accomplishment" to players? So. That's the sort of corporation we're talking about. So it's no surprise its marketing team tried to boss the creator around, to make something less true to their vision of the game but more marketable. Sex and gore sell; but if they fit that's another can of worms, you know?
Dev team might want to find another publisher for its future games, though. Even if this one sells like ice cream in the desert, odds are EA will try to find ways to punish disobedience.
