They are part of a long running "Game Theory" series. It's really fun to watch :D Makes you think sometimes too. I think this is the same series someone was mentioning last weekend, about how Sonic is actually really slow, and mario is faster.
This mario two parter really makes you think. There's even more mario stuff with rosalina and stuff. All worth watching :)
