Greatest Ever Video Games?

Okay, guys, admit it. In some point of your lives, you HAVE played a video game! The question is, which is the greatest? Now, we all remember the Atari, and the Nintendo, and the Sega. That's all gone to a whole new level in gaming. Nintendo moved to the 3-DS, Playstation moved to PS3, and Microsoft is still on the X-Box 360. Nobody knows where Sega is at this point. In my opinion, I'm a Nintendo gamer. I love the games like Zelda and Mario any day of the week. The question is, in all of these gaming companies, which is the greatest game ever? Well, in my opinion, I'm kind of stuck between Mojang's Minecraft, and Nintendo's Legend of Zelda. I love a good Zelda game, but I also love a game when you can craft, build, break, fight, and now trade. To be honest, my favorite game is Minecraft. I absolutely love that game! That doesn't mean that I won't play Zelda, because that game's good, too! As always, what do you guys think? What, in your opinion, is the greatest game ever?
