It doesn't matter what the other flaws in the game are, it doesn't matter how good the game is, it is always the worst part of the game. I've been playing D&D and D&D video games since they were using 16 bit color isometric maps and they were all turn-based. I don't understand why the original Baldur's Gate games were given that mechanic of the Infinity Engine other than "Lets try this out, it'll be action-packed and give you lots of freedom!." But in the end, it becomes a chaotic mess of things happening that you can't see to understand what's going on half the time. It is also a huge departure from D&D in general which works on turns bound by initiative. There are so many D&D rules purists out there complaining about action economy and here we have this thread saying to throw actions and action economy out the window in favor of a 20+ year old mechanic that wasn't the best then and hasn't aged well (I'd love to play Pillars of Eternity but w/RTwP? HARD PASS, I've tried).
I suppose it's the Baldur's Gate purists that say that it's not BG without RTwP and you know what, if you get what you want you'll be butchering this game for a sense of systematic nostalgia that should have never been born.
