It's not a recap, it's about closure. And the endings are not more than 2. You dominate the brain or you get it to turn off. The rest is window dressing. And the worst part is that the window dressing has barely any variation. Someone has to go octopus or eat brains. That's it.
I agree, the main story has two langely different conclusions:
1. dominate the brain
2. destroy the Brain
But to be honest, what else is there? Can you give me examples of further possible and logical conclusions to this story? I really can't think of any that would make much sense or are satisfying:
3. Deciding you don't want to fight the Elder Brain and instead leave Baldur's Gate? Role credits?
4. Freeing the elder Brain form the Crown of Karsus and letting it return to its original Mind Flayer colony?
I think 1 & 2 are the only logical conlusions to the story and yes, the rest is window dressing, but that's where all the flavor is. For example, it felt great to fight alongside Orpheus, especially because I romanced Lae'Zel.
