D&D General Do THIS, WotC!

[GuyBoy]

Greyhawk.
With an adventure path running from levels 1-20, and focussing on Iuz as the final BBEG.

 

[the Jester]

Something in the style of 3e's Unearthed Arcana- a book of alternate rules, allowing for a lot more customization and fine tuning of the game toward different playstyles.

 

[Lidgar]

A book of encounters, similar to the old Book of Lairs I and II. Short encounters that cover a variety of encounters and environments.

 

[Steampunkette]

Pay me a bunch of money to redo Paranormal Power as an official 5e product with full support and editors.

 

[THEMNGMNT]

GAMMA WORLD.

But here's the thing...

It's by Rob Shwalb. He's got a game called Punkapocalyptic that demonstrates he could have a lot of fun in post-apocalyptic gonzo setting.

 

[Muso]

Birthright!

WoTC should do an OSR equivalent via pdf and special order books. They would make a lot of money.

For the life of me, I just don't understand why WotC didn't years (or decades) ago offer a simpler variant, even bringing back "Basic" vs. "Advanced," but in a more literal sense.

I suppose, maybe, they didn't want to confuse people, or compete against themselves. But I think a more "basic D&D" could potentially be very popular, and give a stronger on-ramp to the fuller game (but wouldn't have to).

Another: Some kind of Epic/Immortal Handbook. Not just 16-20 level, but 21 and beyond. Rules for attaining truly mythic status, even demigodhood at levels 30+.

 

[Gradine]

A player option book, but one that is focused on less on species and sub-classes and provide more options to customize characters through feats. More opportunities to pursue a facsimile of multiclassing through feats rather than traditional multiclassing rules. Get us closer to that fabled modularity we used to hear so much about, back in the day.
