Thanks for the tip, Yora (and everyone for the insight). Would be great to move the thread over to Worldbuilding [but...how?] -- I hadn't even noticed it! Will peruse for sure; but in the meantime, I'd love to hear other success and horror stories from the memory vaults...

Here's a softball for the moment: What happens when refluffing character classes tips into a redesign of game mechanics? What are some less-obvious consequences of playing fast and loose with those mechanics?
