As some readers may remember my Sunday group switched from Microlite75 to Swords & Wizardry Complete for a few weeks so I could work on converting some of the Microlite75 rules to Swords & Wizardry Complete. The playtest sessions themselves turned out to be a disaster with players too sick to play, players with family members sick, players suddenly sent out of town by their boss, etc. We had more people missing sessions over the last 2 months than over the prior 18 months. This is no reflection on S&W as everyone enjoyed playing it and even with all the real world disruptions, I got enough playtesting in too know what I really need to work on before I can write up the promised Swords & Wizardry supplement?.
We have now switched back to our regular Wilderlands campaign using Microlite75. One thing moved from Swords & Wizardry Complete to our Microlite75 campaign: 0e style saving throws. I've never been happy with 3e-style saving throws as they don't have anything like the effect on classes that the 0e style saves do. For example, high level 0e fighters can easily take on high-level mages because their saving throws are excellent.
My players were surprised to find that they liked the 0e style saves too. So, 0e-like saving throw tables have become part of our Microlite75 campaign. They are needing a bit of tweaking but they are working. The next edition (1.1?) of Microlite75 will probably include a 0e-style saving throw table as the standard rule with the current 3e style saving throws as an optional replacement.
