Let's see...possibilities...please state your preferences (if more than one in order)
Option One: Resurrect the old Pretty Sailor Soldier game and pick up where it left off, adding new players as needed. (Note this game requires ten players including myself).
Option Two: Sailor Moon goes to summer camp. A hentai focused game where the senshi find themselves in a negaverse trap with two problems. They're in some sort of pocket dimension and have to figure out how to escape. If that isn't bad enough, then their sex drives have been ramped up to the point that they're nymphos and every time they have sex they get that much more nymphotic. So it's a race against their own hormones or they get trapped there forever doing nothing but having sex.... Would have knights (male counterparts to the senshi) and villians.
Option Three: Silver Millenium campaign. The campaign will take place on one of the planets (Venus most likely because that's the one with the most information) and include such marvelous plot details as a simmering undercurrent to prevent a civil war between noble houses, evil villians, etc, etc, etc.
Option Four: Evangelion campaign. Based loosely on a short story of mine where the last angel in the series wasn't the last angel. An invasion by a horde of 'superangels' and their minions which resulted in loss of over 90% of the population and devistation of half the planet. Players will be divided into two EVA groups (Rei 2/Shinji in China and Asuka/Jared in Europe). Pilots, NERV support personnel, line infantry, civilians to name a few possibilities
