I would like to use only things I have in physical form so I can use a banker's box to hold it. This is an idea picked up from Twyla Tharp's The Creative Habit which I'll discuss tomorrow.
1) Start with any ol' D&D-esque ruleset, though a simpler system without alot of fiddly bits probably works better here.
2) Add some supplementary rules material. You're primarily looking for new Gygaxian building blocks (classes, races, spells, monsters, magic items, etc) to drop into the game. In this recipe you want exactly two different sources for this stuff, one of which is easy to put into your game, like adding Mutant Future as a source of monsters and treasures to your Labyrinth Lord game. For the other one choose something that might be a little harder to fit into your system of choice without some work.
I like to call these the near and far supplements. For LotFP I will define a "near" supplement as anything written to be directly compatible with TSR D&D. The only conversion that will really be needed is armor class and perhaps a few other things like magic resistance.
The physical rule has the biggest effect here as my first choice, Monster Manual 2, isn't on the bookshelf. I do want a monster book as this is one area where LotFP is pretty empty. I understand Raggi has done this for philosophical reasons but a collection of monsters is useful for me. One reason I'd like the MM2 is the players are much less likely to be familiar. The other is has the section on mapping rarity to custom encounter tables. In fact, that section is why I first bout the MM2 back in the day.
Lacking the MM2 and not wanting to use the Fiend Folio the next choice on my shelf is Monsters of Myth and Legend from the old Mayfair Games Role Aids line. It contains simple background and monsters from six different real world traditions: American Indian, Australian Aborigine, Chinese, Greek, Irish, and Norse mythologies. That looks like a good fit. It's material can provide a basic outline for six different regions.
Now that we've picked a near supplement let's look for a far supplement. Scanning the shelf I want something far not only in a rules sense but in a genre/setting sense. Instead of another fantasy book I'd like something a little different. I'm not interested into doing something more science fantasy like but maybe something from a horror or modern-mystical setting. Looking at the shelves two choices jump out at me, Mystic China and Through the Glass Darkly. Both books are from Palladium and are for their Ninjas & Superspies and Nightbane games respectively.
Looking through both books they both add several classes and quite a few magic spells. However, I'm going to go with Mystic China for a few reasons. First, while I'm not sure I want to use new character classes early out of the gate if I do at some point Mystic China's are more than just magic user types. Second, while the idea of living magic is very interesting I'm not sure that's a direction I'd like to take. Finally, there is some synergy in my two gaming supplements in that both try to provide some Chinese material. I doubt either is going to provide a real Chinese experience (Mystic China does provide a few pages on quick and dirty feel) but I've never run a campaign with an East Asia filtered through typical American rpg sensibilities campaign. Doing something new is always a good exercise.
Tomorrow we'll move onto step three which is selecting a limited amount of fluff to use as inspiration. Then we'll put it all in a banker's box and post a photo plus discuss the banker's box idea.
