Sarafan: Most of D&D computer games are based on real time combat.
I wouldn't say that, as there is a sizeable number of D&D computer games, mostly older games, that are turn-based.
In particular:
* All the RPGs in the Forgotten Realms Collection 2 availabe here (that's 7 games, one of which is Unlimited Adventures; note that I am not counting Hillsfar as an RPG here)
* The Krynn series (3 games)
* The Dark Sun games (2 games; not coutning the online one here)
* The other game with the Pool of Radiance title
* Temple of Elemental Evil (of course)
That's 14 games, which is a sizeable number of games, and is in particuar enough so I wouldn't consider the ones that are real time to be "most".
bengeddes: Yes that made my heart stop. I had to part ways with the Divinity series after they went turn-based, despite adoring the first several Larian titles. I am all pins and needles waiting to hear if BG3 will be turn-based or real-time with active pause.
borsook: Yes, I want it to be turn-based, like 2 last Divinity games, which are brilliant thanks to that. I am afraid they will go with real-time with pause, which was the biggest fault of BG games, using the Divinity system would be a dream come true.
I agree; the real time with pause combat is one of the worst things about the IE engine games; the way I see it, it combines the worst of turn based and real time combat while lacking both the rhythm of turn-based and the fluidity of real-time. (Just watch any video of a non-trivial combat in these games and notice how time keeps stopping constantly, or, of course, play the game and observe.)
Sarafan: Simply the combat became too slow for my liking.
Slowness isn't truly the fault of being turn-based; it's more the fault of things like the interface, the speed of animations, the fact that you have to deal with character positioning, and the relative balance of HP, damage, and accuracy/evasion. (That balance is really not well thought out in AD&D; at low levels, attacks miss way too often (making battles heavily RNG dependent), and at higher levels, HP grows faster than damage, particularly physical damage (and this problem is worse in 3e than 2e because at least 2e reduces HP gains at higher levels).
Perhaps somebody who has played D&D 5e could chime in as to whether that edition fixed the balance issues that slow combat down?
