Now understand this: You've got to give anyone under the age of 20 a break for not playing this one, but now that it's available again via Nintendo's eShop channel on the Nintendo 3DS, you've got absolutely no excuse.
Just go now and spend the four bucks on Super Mario Land 2: Six Golden Coins. Discover the origins of Wario. Enjoy the best handheld Mario game to date. Seriously, we'll wait for you here. Just go have fun and then come back.
For the rest of you, make sure to download the FREE copy of The Legend of Zelda: Four Swords on your DSi or 3DS. It's free, it's awesome, and you probably didn't play it on the Game Boy Advance or Gamecube… because you weren't my friends in high school. 🙁
