I could hear the yelling from my room. My oldest two children were playing Minecraft in the living room, and I had no doubt the yelling was related to the game. Sighing deeply and thinking to myself (not for the first time) that video games are more trouble than they’re worth, I went out to play referee. Turns out one of my boys had blown up his brother’s house and his stash of diamonds. Having never played the game myself, I didn’t know what the big deal was, but my son insisted he’d worked really hard to build his house and accumulate the diamonds. Then, just like that, it was gone, and he couldn’t get it back. One thoughtless (malicious, perhaps?) action had undone everything he’d worked so hard to build.
