If your hatred of (and resulting need to kill) orcs has historically been outweighed by your commendably responsible fiscal nature in these trying economic times, you may not yet have acquired Robot Entertainment's Orcs Must Die!.

Similarly, Orcs Must Die 2 has had 10 percent brutally chopped off its pre-order price -- think of it as an investment in a sustainable future-hatred of orcs. Investing is what grown-ups do.
