Hey all, i'm recently running a one time adventure combining Star Wars and 3.5. A dark jedi and a lich have begrudgingly teamed up to unlock the secrets of a dark artifact. The pc's have two characters (one from each system) running independently from each other. The actions in the one group affect the situations of the other and vice versa. The finally involves the players to choose their favorite character and confront the two villains as the climax.
Both games are made by Wizards and it is pretty easily adaptable. But my question is there any history of crossing systems in publication? Or for those who have done it privately what did you all do? What were the biggest pitfalls? I'm actually interested in anything people have to say about pairing the greatest R.P.G. of D&D with other systems. Thanks.

( i peed my pants a little when the p.c. wizard shrunk one of the AT-ST's legs and when the heroic jedi had some lightsabery goodness through hordes of undead....ahh sweet nerd worlds colliding.)

i rely heavily on a musical atmosphere when gaming. it enhances the story-telling and experience in any role playing session. When a battle begins, or a creepy dungeon opens to another secret level the music is there for a great accent to the story. with technology being what it is i've begun to create cd's for each adventure i run fitting tracks to descriptions and encounters. I think music goes hand and hand with gaming. (there are some cd's for sale at the piazo store and i would love it if people reviewed all of them.)
i have over 40 gaming cd's mostly comprised of movie sound tracks that i bring in my gamer bag when i role play.
that being said, i wrote a bardic adveture where each song gave clues furthering the plot along. i even used some old poems and put them to simple chords on the guitar (rudyard kiplings "smuggler's song" is awsome.) At the end each player, (all of the PC's had at least one rank in bard) had 20 minutes to create a piece to the puzzle using their bardic skills. whether it be a poem, a sketch, a song, a monologue, or a story. half of the people loved it, the others relied on their performance dice roles. Did i forget to mention half of the people in the party were actors?
Dungeon could publish music and lyrics, i would love it, but how many gamers are going to whip out their keyboards and start singing about dragon mating season. the point of this really long post is....the people who play bards like to perform and will. I find they are more satisfied when they bring their original piece of art to the table.

To paraphrase Heraclitus "All things are beautiful in the eyes of god; it is men who deem them good or evil." With a little creative talent any adventure published in big "D" magazine can be tweaked for the foul or remain for the blameless. But even with The Book of Vile Darkness (which does make for very enjoyable abominable villians as Solomani said), D&D is geared toward the heroic. Now i played some fun and evil PC's but the longevity of these characters was akin to a fruit fly. There also was an instance of falling a couple (o.k. more than a couple) powers checks in Ravenloft and finding myself an NPC.
But the beauty of evil adventures lies in the characters themselves not in how many villagers they eat or what cleric they have to sacrifice(a respectful nod to Nicolas Logue's post.) To me the most enjoyable aspect of evil (besides the villain) is the slightly evil character in a good aligned party. For one you never have to worry about reaccurring enemies. Or if you are the DM, use Vile Darkness to bring them back extremely more diabolical.
