Today I played Minecraft for about 5 hours and decided to make it my new tool of choice in cases of boredom. Even if you don't play with other peoples (registration required) it's fucking awesome - build all the things you can imagine! I love it. It's better than any multiplayer game I ever "played". It's not just a game - it's some kind of art exchange, communication, collaboration and whatever not! I love the concept, I love the simplistic presentation. But there should be a more effective way to protect you from grievers. It's just an awesome tool (or game if you want). You need to test it!
