Well, I posted a link in the other thread. There's also one in my profile to the older stuff (Gee, I really need to update it all...)
Anyway, the whole campaign has been going for about a year and a half. I've been enjoying it, and the players keep coming back, so I guess that's a good sign. Basically, when I started it, I didn't want to deviate too much from the core D&D rules, so I made it very clear up front that the campaign would NOT be historically accurate. There are all the standard classes, with spellcasters being rarer than typical D&D. It's during the dark ages. The Romans/Byzantines are in power, orcs are the barbarians, and goblins have been "domesticated" (they're the slaves).
Oh, I also have used the Manual of the Planes to good use. I used the myths of the Fairy Realms, and extended the idea to include a realm of Dragons, and another realm of Giants. These are each alternate material planes, accessible through the Shadow Realm. The fantasy races have migrated to earth from these realms in ages past.
Originally, the PCs started out in central Europe, along the barbarian frontiers. They tracked down an enemy Shadow Elf (simply an elf with the shadow creature template) into the Black Forest, and discovered a portal to the Fairy Realm.
Well, since then, we've had a TPK, and the players have restarted in Egypt, based in Alexandria. Now they're dealing a lot with animal headed people, and trying to figure out what the Snakeman cult of Apep is up to.
There are quite a lot of anachronisms (for example, elves make longbows, dwarves make heavy armor), and gaps from the actual historical record (there are really no atrocities or schisms from the pseudo-Christian religion), but the players seem to take it all in stride. I guess I'm really lucky in that regard.
