For today, we have a new and corrected version of BMoTU in pdf format, now including money, magic items, enhanced experience, traps, hazards and healing, and more gimmicks. Still on a single two-sided 8.5x11 sheet of paper, too ! Yes, rules uberlight !
In all honesty, the new sections are very terse, but hey. It's all on one sheet of paper, darn it! Those of us with limited attention spans and failing memories (i.e a family and a long commute) appreciate that above all else......well, I do, anyway.
