Behold the bewilderingly overpopulated, open world, first person, memory-gobbling RPGs of Brilliant Game Studios.
In The Ultimate Battle Simulator (top) players pit vast armies against one another. Above, 300 Jedi knights versus 60,000 medieval foot soldiers. Or if you prefer, a pitched battle between 20,000 Jedi and 20,000 Darth Mauls.
The Black Masses is a far darker and bloodier journey into crowd simulation, as evidenced above (warning: unremitting gore) by a sequence wherein 10,000 zombies are dismembered by a giant blender.
