Hmm . . . I would:
d20
Create "d20 Core". This book would be the central d20 reference. It would be at the *top of the tree* and all d20 works (including D&D) would stem from it. However, this reference work would not be the "be all and end all" of d20. It would be a "tool-box", of sorts. For example, the Class chapter would show examples on how to make a Class for your own games and also present a Classless system. The book would be as *generic* as possible. It would present Weapon Proficiency (Martial) alongside Weapon Proficiency (firearms), etc. The book would be no bigger than the GURPS Basic Set book which, essentially, achieves the same thing.
D&D 3E
Release D&D *4E* so that it references d20 Core (see above). Of course, D&D 4E will need to tweak, and add to, the rules of d20 Core to create the "D&D" feel. A *fifth edition* will be released only when d20 Core is updated.
GREYHAWK
Give all rights to GREYHAWK back to Gary Gygax.
FORGOTTEN REALMS
Make FR the "default" D&D setting.
Oriental Adventures
Re-release OA for 4E with Kara-Tur as the default setting. Remove all reference to Rokugun. Release the Kara-Tur Campaign Setting as a hardcover book. (AEG can continue to produce suplements for Lot5R.)
Arabian Adventures
Release 4E Arabian Adventures with Zakara as the default setting. Release the Zakara Campaign Setting as a hardcover book (the title Al-Qadim will no longer be used).
PLANESCAPE
Re-instate the Great Wheel cosmology as FR's cosmology. The default Prime Material world for Planescape will now be FR's Toril. (True, the Great Wheel was "shoe-horned" into FR but then a lot of stuff was shoe-horned into FR.) Now that GREYHAWK has been sold to Gary, FR can now have an Outer Planes that is unique to the setting.
SPELLJAMMER
Re-release Spelljammer but make it a bit more *serious*. Realmspace of FR will be the default Crystal Sphere for this setting.
RAVENLOFT
Sell to the highest bidder.
MYSTARA
Sell to the highest bidder.
BIRTHRIGHT
Sell to the highest bidder.
DARKSUN
Sell to the highest bidder.
DRAGONLANCE
Continue deal with Sovereign Stone.
ALTERNATY
Allow another publisher to release Stardrive and/or DarkMatter using d20 if they so wish.
GAMMA WORLD
Continue deal with White Wolf S&S.
AMAZING ENGINE
Sell to highest bidder.
METAMORPHOSIS ALPHA
Hand back rights to James Ward.
BLACKMOOR
Hand back rights to Dave Arneson.
BOOTHILL
Sell to highest bidder.
STAR FRONTIERS
Allow another publisher to produce a d20 version if they so wish.
Have I left anything out?
What would you do?
[My suggestions are not really serious. They make very little financial sense. Oh . . . and I'm not an FR player! If anything, I'm a Greyhawk fan.]
