First of all, the Pirates would totally kick the ninjas assets. You know how easy it is to catch a ball with a hook? You just stick it out there and spear the sucker. And those peg legs, they can whip a mean bicycle kick with those. Not to mention all of the natural advantages afforded by scurvy, lice, and tainted grog. And parrots . . .
The only way those rice-eating, panda-loving, straw-hat-weaving ninjas would win is if the game was played in the dark. Then, they could throw out a poisoned rice-cake, sneak up behind the gluttonous pirate as he's puking his brains out and . . . oh . . . wait . . . wrong game.
For the record:
Pirates
Zombies
Knights
Ninjas
Spacemen
In that order.
