Minecraft can be a bit addicting. But the same can be said about pretty much everything.

The only bad experiences I've ever had was when I was killed by an Enderman in my house. Or the time I got lost in a cave and fell into lava.

Bad experience with minecraft? yeah i was feeding my pigs carrots and i hadnt realized that made them mate. now i have more pigs, too many and i dont have the heart to kill them. And my crops caught on fire. My house also burned to the ground. : P

Red matter explosive blew up under my house
