In some ways, it totally is. In others? Eh...
Minecraft is a lot of things, but one thing it's not is just a game. It never was when it launched and it's still not now that it's...launched. It's always been about more than the thing you click on and click on and click on again. It's been about the way it encourages community, gets people talking, sharing and co-operating.
Minecraft has also long been about the scene around the game as much, if not more, than the game itself. About identifying yourself as a Minecraft fan. There are millions of gamers left cold by the increasing trend of publishers to "dumb down" their offerings, to drive them at light speed towards the lowest common denominator. Many of those cling to Minecraft like a drowning man to a plank. And they hang on tight.
I mean, how many single games or franchises get their own conventions? Call of Duty, the world's biggest video game franchise, has one. And Minecraft has one. And...that's about it. How many games have I ever had fans call me at my home to complain I'd used a YouTube video for a story that didn't show the game in the best possible light? There's Minecraft, and Minecraft alone.
