I thought of this years ago, before Microsoft Surface was even a concept. I imagined the computer keeping track of everything, letting players worry about tactics and role-playing rather than accounting. No more having to draw lines on a dry-erase mat with markers. Doors look like doors, pits look like pits. I thought it would be damn cool when someone made it.
Now someone has made it, and I was wrong: it is not damn cool.
IT IS MOTHERF__KING AWESOME
