I have to say the best vehicle of movement in any game is Yoshi. Some might not call him a vehicle, and I'd have to partially agree, but I really just had to insert a retro game into this thread somehow.
From Mario? The green crocodile thing?
lol yeah- I mean, can any of the other vehicles simply eat the enemies? I mean, sure, they can vaporize them or fill them with led or what have you, but do they put on the facade of a cute and innocent looking yoshi? No, most are obviously machines for destruction. an enemy sees you coming on a giant killer robot, their gonna run, you come into town on a small green lizard, their just gonna laugh, at least until the lizard eats them.
I tried looking at Super Mario World objectively the other day, and it started feeling much darker. I mean, Bowser never actually killed anybody, and yet Mario and Luigi in their quest to "get to know" the princess, are killing all these goombas and koopas, that for all we know are just on their way to work. and then there's yoshi, I mean, you eat a koopa, and you spit out an empty shell- I can imagine yoshi sucks out the delicious koopa from inside it. All to the tune of happy music.
