Nintendium 

The hardest, most durable material known to mankind, discovered by nintendo for usage in their console, the Nintendo Entertainment System (Also known as: NES). Its manufacturing process was perfected sometime before the creation of the Gameboy by Gunpie Yokoi, Nintendo's hardware genius, or "mad scientist", who invented many miraculous toys for children and adults alike, though many would argue they were meant for children.

Since the birth of the Nintendo 64 (IE, N64), Nintendium has become harder to produce or find, as the quality of the Nintendium used in the Nintendo DS (IE, NDS) and Wii (IE, Nintendo Wii?) have been reasonably weaker than their predecessors, though the WiiMote has been known to resist bullets, fly straight through Television Screens, and cause injuries when thrown, and is considered to be encased in the purest, most refined Nintendium seen since Gunpie Yokoi left Nintendo and died.

An asteroid of pure Nintendium is coming towards the earth... We're doomed!!!!!!

Nintendoitis

Nintendoitis (noun) This condition usually occurs after you've played a console game too long. But was prominent with the original Nintendo Entertainment System back in 1985 with the original box controller. After many long hours of gameplay be it Zelda, Mario or Contra or whatever game you were playing, you would begin to feel pain in your thumbs and it would work its way up throughout your hand. But you usually wouldn't stop playing because you wanted to beat the game. But this condition can still occur with just about any game console controller.

Sam: Yo man I'm going to beat this PS3 game.
Tony: Ok I'll go watch a movie.
*three or four hours pass by Tony walks back into the room seeing Sam still at it.*
Tony: So how much further do you have to go in the game?
Sam: I'm almost finished but I'm developing a bad case of Nintendoitis.

Nintenditis

Also known as Gamer's Thumb or Nintendo Thumb, Nintenditis is when some part of your thumb or wrist becomes irritated or swollen due to excessive video game playing. A person with Nintenditis will feel pain or discomfort when bending their thumbs or moving their wrists. Note that this can happen with any finger, and not just the thumb.

I concluded that I had Nintenditis when I noticed a constant pain in my thumb during a game of Super Smash Bros.

Nintendoitis

A condition very common among 8-bit games, but can be applied to any game in which this happens, even if it's not a Nintendo game. It is a condition in which an enemy that was just killed would respawn in the same place if the screen scrolled to the left and then back to the right (or right then left). This condition is most prominent in games like Super Mario Bros. 2

Hey, I just killed that guy! He came back while I was going for that 1up! This game has Nintendoitis bad.
