I think one of the main problems is that some people see "that might not work well in a video game" as being anti-D&D and anti-Baldur's Gate 3.
For example - a true D&D experience would be if there are 37 players/enemies on the screen every single one of them should take a turn, display the dice rolls, etc. That is the correct way to do it, but it takes an eternity and for the wider video game audience it is a pain. So I personally think that Larian's system of "trash mobs" all taking turns at once is a good idea, even though it isn't pure D&D in its implmentation.
I also agree with others in this thread that I think they should have a toggle for this. To turn on a more detailed reaction system vs. something more automated. No clue which one I'd use since I would have to play with both to see which one felt right. But I can definitely see the argument of mass pop-ups making combat take an eternity... though I personally find the current reaction system makes all reaction based skills kind of useless, so I just avoid them... which also seems bad.
Hmmm. No. I have several issues with your comments.
1. "that might not work well in a video game" as being anti-D&D and anti-Baldur's Gate 3. This just isn't true. It's not about who is pro or against D&D or BG. I have been on this forum for 2 years and have not seen any players accuse others of being anti-D&D or BG because someone says something might not work in a video game. I've seen them fight for D&D 5e, myself included, I've seen them say that they think someone is wrong and that it actually WILL work in a video game, but I have never seen someone accuse someone else of being anti-D &D or BG because they think something won't work in a video game.
2. I've NEVER played a D&D session with 37 players/enemies. Ever. That is SO extreme and not the correct way to do it in anyone's book that I have ever seen or heard of.
3. In a video game, turns go faster because you don't have to math or track things yourself, so more enemies and allies doesn't take as long as pen and paper. It might still take a while, but it is in no way the same.
4. Who is complaining about the BG3 mob move and act feature? I thought this was about reactions?
5. Solasta has proven that popups really don't make combat take forever. The worst popups in that game have nothing to do with reactions.
