I知 a big fan of the 1st edition of Warhammer FRP, and was considering it as a basis for a dungeon crawl game in the near future. After looking at the rules again I was concerned about the players not being interested. After much debating I finally decided on using D&D 3.5 as the base system since everyone knew it and most already had the books. Using 3.5 opened up a whole new slew of problems, like rapid advance, epic (or superheroic) feel (Warhammer is anything but "epic"), and the power level of magic users in later levels.
The first compromise I ran across was E6.
This d20 variant allows the characters to advance to level 6 as normal, but after that the only advancement would be a new feat every 5000 exp. This seemed to hit the mark and 6th level is considered by some to be the "sweet spot". Unfortunately, I ran into some resistance from the group, so I kept on searching.
The next book I ran across was
Unearthed Arcana. (via
d20srd.org) I had overlooked this book many times because of the various "alternate races" like the aquatic gnomes or the Jungle Dwarves. After flipping past that I found a bunch of alternate rules which helped tone down the power level and add flavor. Wounds & Vitality, Rituals, Traits, and Action Points are just a few of the items that will make it into the game.
Finally someone pointed me in the direction of a book called
Darkness and Dread by Fantasy Flight Games. If Warhammer d20 was ever made Darkness & Dread is what it would look like. It replaces all the classes with 24 new core classes like beggar, herbalist, worker, artisan, and sewerjack. Most of these classes only go to level 5 with a few exceptions going to level 10. Most of the classes are not weak either, the sewerjack has the best saves of any character I have seen and the Worker, by level 5, will have obtained 4 Stat increases. If one is to multi-class, there are entry requirements. I had to tweak the rules a bit here though, because skill requirements were current level +3 to get into some classes. If the skill happened to be a cross class skill it would be impossible to switch without spending a feat. I have changed this to must have 3 ranks, which will be obtainable after 3rd level. Besides entry requirements for classes, and non standard classes, you can also roll for your beginning class if you so desire.
Other parts of the book deal with horror. These may or may not be used as my plans are not for a horror campaign, but a "low-level" action/adventure game.
The other book I intend to use is
The City State of the Invincible Overlord by Necromancer games.
