My point was that to enter act 3 at all, you have to have made a very big choice with Gale that can only go in one direction. That feels railroady to me.
I agree that you can put the effort in later to turn him away from temptation, but the fact that you are forced to put him in that position to even be in act 3 is bad writing.
I would much preferred to have been given the chance to go supernova as an option to solve the crisis in act 3. Destroy the brain and all of Baldur’s gate with it, to save the continent. Or lure the brain elsewhere and destroy it there.
As it stands it actually makes no sense why all three of the big baddies AND the brain would be in moonrise tower all at once at the end of act 2. It’s almost as though they were written that way JUST for Gale’s choice.
I feel like they had a chance to do a better job of the pacing and really have a proper struggle in act 3 in Gale having to choose between personal power and redemption.
You only get to see their conversation if you choose Gale as your origin character.
There is a surprising number of options for what he does. You can find them all on YouTube, I couldn’t be bother playing through as him.
