Well, Jan and I talked about Conquest of the New World Deluxe Deluxe, with a fixed Americas map. I think a Scramble for Africa Deluxe Deluxe was talked about too - and that would go well with a VEIII civ coming with the WW1 set. They wouldn't be on the same scale as ITRD, so might not be so bad to work on sometime - though I wouldn't think about it until next year.
Smaller scenarios: I have to update the Wonders one at some point, and the rest are too militaristic for my taste (except Polynesia, but Pouakai wanted to do that Deluxe scenario). Although I did want to introduce a religion element to a Fall of Rome Deluxe. But honestly, I don't have time for everything - I do have RL matters that take some time. It's ok for the next three months or so, when I only have two papers between them, but thereafter it'll be much more hectic. So I'm thinking of saving less intensive things like more Deluxe scenarios or Civ updates until then.
