LOL, not doing well in the simulation department in that video. Any ninja that got surrounded by 4 armored samurai warriors would be a dead ninja. Any decent ninja simulator should be a total stealth game, fighting only when absolutely necessary, more like Thief. Also, such a simulation might be incredibly boring, like the ninja who hid for three days in the daimyo's outhouse until he finally came to use it, and assassinated him with a spear up the butt.
