The future is in the videogame industry.
In my opinion the challenge for the game designers will be to find the balance of power between different playable factions in PvP games where someones have higher magic or tech level, for example musketeers vs warmages vs barbarians. If firearms are allowed, then nodoby want to play lowtech maglless characters as barbarians or swashbucklers.
My suggestion are a RTS set in Cerilia (Birthright), other set in Red Steel/Savage Coast to test firearms when the enemies are gunfighters are the PCs primitive savages, and later a Gamma World where to test the new ideas for a d20 Modern 2.0. (for example adding new abilities scores:acuity (astuteness + perception), courage and spirit ( = karma/luck/fate/guardian angel, resistance against supernatural attacks, but also hope and faith in the future). And a free app to be the AI for sole player board game, something like the "Hero Quest" board game, but now with the name "Endless Quest", for +10 children, easy rules to be learnt.
I imagine the ultimate D&D as an asymetric multiplayer where one is the dungeon master, creating rooms, and adding traps and monsters, something like the comingsoon
"Resident Evil: Resistance", with an optional creative mode, like a quest/adventure/missions creators where nPCs with optional dialogues can be added. Even with the option to create machinima movies.
We will see a videogame of Dark Sun, but psionic powers need a lot of playtesting. Ravenloft is perfect for survival horror titles with puzzles and stealth as "the evil within", "silent hill", "resident evil" or "dead space".
Why not a coproduction with Capcom for a beat'em as "Shadow over Mystara"?
Videogames of Dragonlance, for +7 rating, deserve a second chance. I can't be worse than the originals between the last 80's and beginning of 90's.
