Nintendo got them alone in a dark room and told them that if they don't settle, admit and pay something they might be able to pay off in their lifetimes (Nintendo doesn't care about the money, 2.4 million is nothing to them), Nintendo would tie them up in legal battles for years, still making them broke and probably blocking them from doing something new.
Or something.
Fucking corporate shills. Why can't we just all have fun gaming. Piracy increases sales.
