Man, since the confirmation that this title even existed it's almost baffling how stingy of any real information Larian has been.
They went through E3, Gamescom and PAX with literally nothing to show or confirm about its structure, making their public apparitions rather awkward for how pointless and inconstant they felt.
It makes almost the impression that the reveal itself was some sort of premature ejaculation and they have very little to say about it in the first place.
Pretty simple... They saw how many fans didn't want TB, realized they did not want to lose thousands of pre-order sales, and are now scrambling to add RTwP.
Or.... they could have read this forum and realized the exact opposite, and are currently adding a TB mode to make more people happy.
Either way, it doesn't really matter. The most important things they need to deliver on is to make sure BG3 possesses what you posted about in the other thread... that it has the same sheer
size, scope and variety of what made Baldur's Gate 1 and 2 outstanding classics.
