So I happened to have a chance to play this game, and let me say, it is awesome.
If you get a chance, purchase it, play the free creative mode on the minecraft website, or even obtain the game by other methods. Definitely worth checking out.
And don't let the pixel-graphics bother you, that's all part of the Minecraft-magic (yeah, I know, sounds cheesy).
And let me say, I'd be willing to bet Minecraft will be among all those classic games that will be played years and years after it's released. Just as the classic Doom games are still played, Duke Nukem 3D, Super Mario, all of those classics.
Here's some links to help you out, should you get the urge to check out Minecraft:

Also, watch out for idiots that look to label you as a griefer in multiplayer creative mode. Destroy even a single block on their building, and they will go berserk. It's amusing, though, if you consider doing it.
