what is Minecraft all about?

blocks.

It's just this giant sandbox game, with monsters trying to kill you. You can create anything you can imagine. Think of it as Lego's with survival mode aspects. I own it, and it's fun to play occasionally but I end up finding myself pretty bored soon after I start playing. It's not hard to get the best materials and make something cool by a few days or even a few hours. You can try the classic version on their website, it's very different than the new version though. Personally, as I do find it fun, I would take my money back for it if I could. I don't play it enough for it to be worth 20$.
