Alea Iacta Est

In no particular order...

Fading Suns

It's knights, nobles, priests and guilds, recycled in space. It's Dune meets Warhammer 40,000, and it's awesome. This game would probably be much like my last (it might even be a re-run of my last, since that went so well and the original party are too far away to play): the nobles of the party will be Questing Knights and everyone else Questing Cohorts, in glorious service of the Emperor.

Something horror

I don't know what system, and I don't quite know what setting. Traditionally I've steered clear of horror - it's hard to run and not all that easy to play - but I think now might be a good time for another go. It might be Ravenloft, although using BRP rather than D&D. Who knows.

Pendragon

It's knights (probably only knights, but I'm happy to have female ones in the game), nobles, priests and wizards, in something like Arthurian Britain. Lots of time-skipping for an epic feel as characters eventually age and get replaced by their heirs.
