We know Newerwinter Nights and Baldur's Gate have been sold very good, but we can't say the same about other D&D videogames. Today multiplayer online videogames are a too risky bet. I advice off-line videogames. Today a collab with a videogame by other company is a faster and safer option.
Hasbro is more focused into D&D as multimedia franchise. The TTRPG is only one of the income sources.
A comic publisher could be one of the future acquisitions.
With the right writters Ravenloft could be sold as gothic horror or supernatural romance novels.
Larian, and other studios, wanted the licence because this would help very much to earn prestige if the product was sucessful. I guess other studios coud get a D&D licence, but not in FR but in other setting.
* Hasbro should make children started to be interested into D&D monsters, but as a cheap hobby. Parents don't want to spend too much.
* A DLC could work as a spiritual sequel of Planescape.
Maybe a videogame studio could get the licence of Dark Sun, but Hasbro would clean the hands about any possible controversy.
