It is something I have already discussed in the shoutbox at some point to get some ideas going, but the basic idea is as following:
A group of friends is playing dungeons and dragons. Because their dice went missing the last time, one of them got some new ones from a nearby voodoo store. Ignoring the shopkeeper's warning that voodoo is not a toy, they decided to use them for their game all the same... only to end up inside of their gameworld, stuck inside the bodies of their characters. As if that wasn't bad enough, the world quickly takes a turn for the worse and they have to save it in the hopes of getting out.
I'm thinking a first level start, because it would make more sense RP-wise. They weren't exactly warriors or sorcerers in the real world, so starting them out learning the ropes works best.
Meta-gaming would be allowed, based on the knowledge of the real-world character. A total DnD geek might know exactly how to beat a gelatinous cube, where as somebody who joined the session for the first time would be left relatively clueless as to what is going on. They did not lose their memory after going inside their characters.
Characters could become drastically different. Think the six-foot tall jock who joined his first session suddenly being stuck in a halfling wizard's body, the flat-chested geeky girl of the group suddenly being a towering, busty barbarian, the guy who always plays female characters getting stuck in a female body.
This is not a sign-up thread, I'm mostly just looking to see who would be interested and who has ideas to share. There's no need to post character profiles yet. I'd love some ideas on what kind of adventure the RP would be, etc.
