It's really tough to wrap your head around. 5th editions relatively simple mechanics and clear-cut archetypes and bloatless core frame is so well suited for a video game, that it's actually ridiculous that a real attempt hasn't been made. Sword Coast Legends was an abomination, that had very little to do with 5E. Unfortunately, it seems that their failed attempt has scared potential game producers off - and as far as I've heard (can't remember where) the IP for a D&D game is very expensive, and comes with a lot of strings attached, so it seems that the companies that would have a chance at doing it right, prefer to do their own thing instead (PoE 2, Divinity: Original Sin 2, etc.).
