Eh, there's only one game that never really started with them on this forum. Anyway, if not enough people go for it, I have a second idea. The theme is somewhat similar to a mix between a zombie survival thing like I'm checking interest for now and *Dramatic Pause* Halo.
Mostly I was thinking of crashing a interstellar cruise ship or the like through a wormhole and onto an alien planet in the middle of a war. I'm not actually going to use any aliens from Halo or zombies. Just that it's thematically similar since you get more or less stranded on a world covered with aliens who will kill you on site more than half the time. Of course, there would also be the fun challenge of having the characters figure out how to use alien tech without maiming themselves.
You said you wanted something "Original", and then gave an example that was being used by most of the hentai RPs that exist - i.e., an unoriginal idea.
HEATHEN! BURNZ HIM!
And I haven't found any RP that has flood involved yet so it's pretty original to me.
I mean, a little parasite tapping into your mind and making you have endless amount of Libdo...
