Back at Act 3 in my second playthrough after aborting the first and uuugh I can't be bothered. It really does run out of steam pretty hard towards the end, and I don't care about the main plot at all so I don't even have that as a motivattion to continue.
First act is absolutely outstanding, second is decent, but after that it's just so hard to give a shit. I hate my character too, she's a fucking gnome.
Also, I know other people have confirmed it, but: yeah, the reactivity/C&C is almost entirely illusory in this game. To make the comparison yet again, we're pretty much talking Dragon Age tier.
I think Larian have made one of the best RPGs in the past decade... and it's called Baldur's Gate 3 Act 1.
