Since the 1970's, I've used critical hit and failures tables in all of my games with great enjoyment. There are even plenty to be found online with a simple search, or one could just create their own. Of course, to make it work, imo, the baddies must also follow the critical hit and failure tables in each game. If you gotta have balance, then this is the way to go. To me, it just brings more enjoyment to the game.
What say the rest of you? Please recount any stories you may have regarding these tables.
