To control prices, mostly. For example, they don't want their Japanese customers importing their games from Korea for cheaper. With region locking, they can set the price in each region according to what people in that region are willing and able to pay. Also because Nintendo hates America.
Because the United States does not officially recognize the Mushroom Kingdom as a sovereign nation.

Because Soneeds what Ninten do.
What if Sony bought Nintendo?
Well it doesn't look like it'll suck as much as it was going to, now that they changed a lot of those restrictions on used games and online connections. It still sucks because it's stupidly expensive for little to no benefit over the Playstation 4 and because it still requires a subscription to play online which is also more expensive than the PS4's required subscription. Meanwhile, it's still free to play online on PC or Wii U. And half its features aren't available in most of the world.

Why does Mario wear a hat?
It's part of his work uniform and helps to make the Super Mario Bros. Plumbing Co. brand recognizable.
This is a little known fact, but Mario actually is Mexican. Nintendo has only recently tried to cover up this fact and claim that he is Italian because they realized that Mexico is part of North America, which, as we all know, Nintendo hates.

He shoots like 8 different weapons in every Mega Man game and you're worried about lemons? If you must know, it's because every robot is weak to lemons.

How do I get married in animal crossing?
First, your friendship with the villager you want to marry has to be as high as possible. You'll be able to tell that it's high enough when they've given you three or more pictures of themselves. Next, buy five royal crowns, wrap them (you can buy wrapping paper at the store), and send them to the villager you want to marry, one at at time, on five consecutive days. The last letter must arrive on that character's birthday. (For a list of birthdays, check here.) On each letter write out "Will", "you", "marry", "me", "?" without quotes and with only one word per letter. The last letter will only contain a question mark. After that, the villager will have a 30% chance of accepting your offer and will approach you with their response, as they do with public works project suggestions, sometime during the next six months.
