To clairfy, I am not concerned about any merger, just asking the question. D&D as I have seen it no longer resembles anything that I indentify with

OSRIC/Castles & Crusades all the way baby!
In any case, I would like to see:
Temple of Ele(minster)'s Mental Evil
Uh Oh! Is that a Demoness Lady Fungi in your basement?! Elminster, that irrascable wizard is up to his old tricks again of confounding adventurers by sending them on quests into various parts of his tower: They must recover gems and a golden skull in order to woo the lovely girl who has moved into his downstairs apartment. Little do the adventurers know that this girl is none other than Zuggtmoy herself! The players will soon uncover a nefarious plot of rent-dodging (captializing on Elminster's alzheimers as to what day is 'rent-day'....and that he has inadventently added an extra E to his name to make the title work...) when they discover that Lhaeo's outer office has subletted to Lolth; home on summer break, jobless and not a penny to her name! For 4-6 characters of Intelligence of 6 or less.
