I think ultimately the decision for TB was rather simple: Turn-based is far more accessible to a much larger population of gamers (see Pokémon), it's something the company is experienced with, it's far easier to balance for and it makes more sense with some of the mechanics they're trying out.
I strongly disagree about why TB was chosen for this game. The decision had nothing to do with more accessibility or even the silly argument that the PnP game is TB so the video game also must be TB (which btw Larian devs themselves have refuted by admitting that one could make a RTwP game using D&D 5e rules just fine), although Larian dev's personal preference probably did make a difference. It was chosen because it facilitates multiplayer so much better than RTwP. That's the bottom line. This game is first and foremost an MP game, and all game design decisions - from the combat system to party size to others - have been made firstly to facilitate MP. And for me, *this* is the true deal-breaker, not that the game is TB per se.

I do hope that those who prefer RTwP are able to enjoy the game for what it is and (if it's a true BG game) even find it to be a great entry like New Vegas was to Fallout despite using Bethesda's assets/engine.
You have my respect for saying PoE was a good game even though you did not like its combat system.
