Not suited to RPGs?
D&D was the flagship of isometric RPGs with Baldurs Gate and dominated that market. This dominance even extended into the 3D RPG market for some time with Neverwinter Nights. And before that were the Gold Box games. D&D always had a strong presence on the video game market until the end of 3E when Atari died.
But now, when isometric RPGs have made a comeback through kickstarter the only thing Hasbro managed to do are bad to mediocre games like Sword Coast Legends.
Isometric RPGs are not AAA titles. That's why
Pillars of Eternity and
Divinity: Original Sin had to go through Kickstarter to get the capital needed to make them.
And again, therein is the issue. Would either Obsidian Entertainment or Larian Studios been interested in making their respective games Dungeons & Dragons games? I don't know. But if they had to go through Kickstarter to get their funding... would Hasbro have licensed their D&D name to them prior to the KS, and would Obsidian/Larian have had to pay the licensing fee prior to seeing if the KS funded as well? Would they have gotten their licensing fee back had the KS not funded? And once the KS was over and they both GOT the money they needed for their respective games... it showed that they didn't need the D&D license in order to be able to make their games in the first place. Which means they kept all the monies themselves for having an original IP.
So we can throw isometric games out the window. No company that has the money to both pay the license fee *and* can subsidize the game without having to go through Kickstarter most likely isn't going to make an isometric RPG, because the audience for those games is much, much smaller and would be harder to get their investment back.
What's after that? First person RPGs then, like we have with Skyrim, Dragon Age, and WoW. What do they and all the other current popular first-person games have in common? They aren't turn-based. They are action games. Which means that any game with a D&D theme you try to create at that level is not going to be able to be completely faithful to actual 5E D&D mechanics, because those are grid and turn-based. The best we could get would be Dragon Age-like, which does allow for pausing after each turn to queue up subsequent moves. But even then... when you don't have it pausing, the game runs like an action RPG. Which is fine! I like action RPGs just great. But everyone here is clamoring for a game using 5E D&D mechanics, which in the context of action RPGs, is not completely suited and most likely liberties in how the game works will be made.
Could you get close to D&D 5E? Sure, maybe. But would just being close be enough for people? I don't see how... seeing as how if games like Skyrim and Dragon Age aren't "fantasy sword and sorcery" close enough to count as a D&D game, then obviously whatever is made has to be even more faithful (and presumably have all the names be Forgotten Realms names.)
Which again comes down to some company who can afford to make a game on the level of Skyrim and Dragon Age, be willing to pay for the license and not own their own IP. And thus why no one is stepping up.
No one wants to make your D&D heartbreaker videogame. Because anyone who can doesn't want to pay for the IP. And the company who does own the IP doesn't make their own videogames. So we're out of luck. And there's nothing anyone can do about it.
