Wonderful! Thanks, guys!
You know, Minecraft NOT on peaceful mode is still one of the most relaxing experiences I know. Sure, there are monsters at night, but you can choose what to do. If you're adventurous, sure, you can go spelunking. But if you aren't, you can just stay at home and craft some nifty things.
You know those relaxation exercises where you're supposed to tense your whole body up for 30 seconds, then release? I think Minecraft is something like that. After all, when it gets dark, you can just go inside. It's the care we take to create a safe environment that really makes us relax, in this game, I think.
