All Flesh Must Be Eaten (AFMBE) has an odd d10 system where the 10s are SORT of exploding, and the 1s are SORT of "exploding" in the opposite way. Here's how it works: 1d10 rolled. On a 10, you roll a second d10 and subtract 5 from it and then add the result (IF higher than 5) to the original roll. On a 1, you roll again, subtract 5, and if the result is negative, the negative roll replaces the first roll. If the second roll is between 5-10, the roll remains a 1, if the second roll is a 2, 3 or 4, respectively, the result is -3, -2, -1, etc. If the second roll is a 1, the prior roll is replaced by a -5 and the player must roll again. Holy crap. Alright, I've tried setting up macros for this, and its a nightmare. Does anybody have any experience with this stuff, or is this best put into the "holy crap too much work" category, and not worrying about it? Macros would make a GMs life easy, but if its impossible, I'll figure something else out.
