Read it so you don't have to - someone found a choice you can make in the second act that counts as an ending. So, they basically ran through act one and made that decision immediately.
They did not play through to what anyone would actually consider the end of the game.
I reckon you could just keep hitting space bar or A to skip all the dialogue, run directly to the exit to Act 2 (ignoring the grove, the forest etc), and just go there directly. I'm not sure there's anything you actually need to do more you move on.
Side question - Can someone try and define the line between the acts without spoiling? I just hit level 8 and found the nightsong last night. I think I'm in Act 2? Was kinda expecting major cutscenes or narration like DOS and BG2 to define them.
All the prompts I've seen saying to tie up my loose ends were misleading considering I could still go back and finish things. Going to the mountains or the gith creche, entering the under dark and the shadow cursed land... The only one with slightly different verbiage was when I entered the prism, and that was the only one that actually made it where I couldn't come back from shit.
It was a bit annoying, because up to that point I'd been told the same thing with different words and it didn't mean jack, so I figured this time wouldn't be different and it ended up killing a ton of people I know I can save. 😩
It didn't mention the act at any time, and from what other players have been talking about I am pretty fucking sure I got the ending this speedrunner did because the game basically ended at Ketheric my first run.
I got a prompt but I was still able to go back to all the places so I was just like sure? Compared to DOS and BG2 leaving acts/chapters had stuff not just a vague prompt
