Some times I imagine a LEGO version of Spelljammer. It seems enoughly child-friendly, and enough exotic for the eyes of the little children, but not too bizare for the parents. Let's imagine minifigures of autognomes, giffs, plasmoids or three-kens.
The controversy of the OGL caused a lot of damage to the prestige of the brand, but it was their fault. Some times some CEOs are people without empathy and they can't understand the point of view by the clients.
* A videogame of Hero Quest is possible, but it would be more "serie B". A videogame of Dragonlance is also possible, but I imagine it with the option to change the characters, and if we want an AAA then we will have to await a lot of time.
A D&D no-CRPG videogame is possible, for example a RTS, a horror survival in Ravenloft, a city-buidling or a farm simulation. Jackandor could be a survival in the jungle.
* Larian can be very proud with their work, but I suspect they don't want to be too linked with D&D. I could bet their next project will be more independient, but maybe easy to be adapted to D&D if WotC wanted to publish the licence.
Maybe other studios would interested into a no-FR licence, like Greyhawk or Mystara. The goal would be earn prestige for the company.
* Hero Quest is too expensive, with a lot of miniatures, and it is not the right product to sell licenced versions.
* Paramount could be interested into Mystara's Hollow World as a variant version of Jurrasic World. The classic dinosaurs but with magic and other monsters.
