I, as well, think The Ice Warriors would be great to see. I also think Fenric could be a good one to use. THE CURSE OF FENRIC is still one of my favorite stories. Also, what about The King Vampire from STATE OF DECAY?
Ooooh, i'm liking the Vampire idea a lot Dream Lord. For some unknown reason State of Decay always gets stick from fandom but I really enjoyed it. Same with Fenric - perhaps a story tying the two together?
My main gripe against State of Decay is that it has an incredibly weak resolution. I mean, you drop a rocket from space, it goes straight through a vampire's heart and doesn't even hurt people a few yards away? C'mon now. Till then, a decent story, though not one of my favourites.
