It was already in an interview that they are not adding real time with pause and plan to keep the game turn based which is something that personally I dont mind and think is a good option to the game. There are crpgs that do use realtime with pause. For those that are interested in real time combat. But real time combat isnt what DnD is meant to play as. Which was the concept behind what balders gate 3 was always intended to be which was stated before the game was released. If they added it for people who wanted it I personally wouldnt complain but honestly the combat system would be garbage to using tactics when you use real time with pause at that point why not just play a hack and slash game or an MMo. As the concept is basically the same.
This is just an opinion but real time with pause in terms of DnD based combat completely defeats the entire idea behind it being a DND based game. Ive had no issues getting through even large combat sequences quickly even when your talking 10 + goblins its not hard to thin the numbers quickly enough to make the npc turns fly by fast enough that its not annoying in slightest. If its taking you an hour to get through a combat sequence your probably not doing the fight in a tactically sound way and you can find more efficient ways to do the fight. Currently this patch the most difficult fight ive had overall was the minotaurs which took twice as long as previous patches but other fights like spider matriach ended in 2 rounds of combat or less. Generally just taking an efficient approach to how you initiate the combat is sufficient to make the fights short. Either by thinning enemy numbers quickly or focus firing more threatening targets down quickly you can generally clear most of the fights taking little to no damage to the point you shouldnt need a long rest for 3-4 fights even unless your using a caster heavy party.
I'm glad larian has decided to stick with turn based combat as a game and wish more companies were designing games with turn based combat options for games in mind.
RTwP was a terrible system for BG1/2. It's a terrible system to use for any game that is attempting to adapt a turn-based tabletop system to a videogame.
That's why it works so well for Dragon Agae: Origins, that's probably the best implementation of RTwP. They were using their own game system, they were able to tailor combat mechanics to fit RTwP instead of trying to shoehorn in turn-based mechanics to fit a real-time system.
The entire concept behind bg 3 was to bring table top to pc which they have done a decient job while the rules implimentation hasnt been as accurate as solasta the mechanics are fine and the turn based combat is very well adapted some of the mechanics would not be as viable if you took it out of turn based and would not play as smoothly or feel close in similarity to DND in anyway what so ever. Real time with pause adaptation IMO is just over done and being implimented into a game doesnt appeal to the audience that does want turn based im not concerned as either way they have already said there is zero chance it will get implimented in the most recient interview with sven which I feel is not in anyway going to hurt the game what so ever with there target audience for the game.
Xcom style and similar games havent implimented turn based combat in a long time so its nice to see someone else focus on turn based games over trying to just do real time with pause because its not something everyone wants in a game. I wish it was being done on a much larger scale with the game like plans to expand the game to crazy levels but its best implimentation of turn based on a long time and i hope they stick with it and add dozens of dlc patchs following the live release with further expanded content.
