I LOVE Minecraft!
I was a late bloomer to the game and my first major exposure was on the PS3. The game is cathartic and relaxing as hell; I can literally lose hours just creating cities, underground layers, and exploring beneath the surface of the game world for hours. I love to make up stories in my head about the worlds I create, who the people are, what they're like, what different cities are in it, what the history behind the world is, pretty much everything. My main map I've been adding to for several years now has probably 150ish hours on it and I love adding a bit more everytime I decide to pop the game in.
I know that all sounds kind of hokey and Minecraft is something made for kids, but I adore the game on so many levels.
