Now I am not yet sure I'll have the time for this but if I am setting it in the same world then I might want to lay a bit of a foundation.
So a theme that has come up a few times in my games, either D&D-like, CineUnisystem or other modern supernatural, is human(oid)s vs reptile invaders. I first got the idea when I was going through the Fiend Folio and I noticed there were a lot of different reptile and amphibian races.
I later (likely through Chill) thought of a snake like race (maybe similar to the "Deceiver" creature) but I could have also been influenced by Doctor Who. In any case they are there, squirming around in my brain.
I would love to take this do something with all these other cool adventures that share a theme, add a bit of backstory (not much) and maybe....just maybe run it all under Astonishing Swordsmen & Sorcerers of Hyperborea.
So here is my thought:
N1 Against the Cult of the Reptile God, levels 1-3 (novice)
U1 The Sinister Secret of Saltmarsh, levels 1-3
U2 Danger at Dunwater, levels 1-4
U3 The Final Enemy, levels 3-5
I1 Dwellers of the Forbidden City, levels 4-7
C1 The Hidden Shrine of Tamoachan, levels 5-7
And that is about as far as I got.
I also have a series of "desert adventures" I want to try.
I3 Pharaoh, levels 5-7
I4 Oasis of the White Palm, levels 6-8
I5 Lost Tomb of Martek, levels 7-9
X4 Master of the Desert Nomads, levels 6-9
X5 Temple of Death, levels 6-10
I9 Day of Al'Akbar, level 8-10.
Gary Gygax's Necropolis, levels 10+
I could fold them into each other. There are 13 here, so I like that number. But they all don't fit in together thematically, unless I am saying that Set is somehow involved. Which could be cool really.
I don't have a copy of Day of Al'Akbar anymore and it has not shown up yet on DriveThruRPG. So I could make it 12 adventures.
Also I could take a page out of True20 and just have everyone go up a level at the end of each adventure. It would make things easy. If so then AS&SH might just be the right choice. I would want to ratchet up the pulp feel. But not really use any Lovecraftian beasties. I am kinda burned out on them really.
Something to consider anyway.
