(I'd love a new thread for Krippler's House Rules, too.)
Me too! I love talking about my stuff.https://vulturesdiary.wordpress.com/house-rules/
These rules were mostly written before I started my campaign almost exactly 1 year ago. A few things have been revised, added or modified during play. I play with a group of friends online, our sessions are ~4 hours long.
The base rules are ACKS which in turn are based on D&D B/X
One of the major changes and least tested aspects is how clerics work. Instead of turning undead they Invoke the Divine
granting themselves temporary hit points and usually a few other bonuses. The few clerics who graced the campaign died or were brutally mauled before getting much use of their abilities. I have never been crazy about the concept of clerics in the first place and I don't know if they really fit the theme or gameplay of the campaign.
I'm very happy with the Binding Wounds rule as it turns water rations into miniature healing potions increasing both the staying power of adventurers and verisimilitude. For a short while I let the wound recovery roll be affected by the Constitution bonus but it felt wrong to further widen the gap between tought and frail characters.
Bodings also work well to give mages some utility beyond their nuke.
A big part of the campaign is the clash of cultures as the supernaturally scrambled geography has created untested boundaries. If you adress someone in their mother tongue you get a large bonus to the reaction roll, the well travelled adventurer will have a lot more luck dealing with foreigners.
Another campaign rule which is not mentioned on the blog is the Pokémon like level system for non-humans @Eero_Tuovinen
suggested in this thread:http://story-games.com/forums/discussion/comment/470179/
So far there are two races using this system, Svartalfr (The Orthogonal Dwarf, http://www.story-games.com/forums/discussion/21466/osr-the-orthogonal-dwarf
) who must first map old stonework before getting a promotion, then they must found a magical forge (which is typically very expensive). The Bushi are diminutive warrior spirits who get their first promotion after slaying 12 enemies and their second when they conquer a throne. They can gain more HD by conqueror more thrones. So far one Svartalfr has returned home to get promoted and one player transformed into a Bushi lord after claiming their throne and staying months in the underworld as their leader.
Any questions and critiques are welcome!
