Also saying that the Watcher achieved nothing is very surface level.
The Watcher found Ukaizo and actually learned what exactly Eothas did and why. This information at least gives people a headstart in solving the broken Wheel shit. Without the Watcher nobody would even know it's broken.
An idiotic achievement that shouldn't need achieving to begin with - if you want to force someone to rise to a do-or-die challenge, it's vital they're
aware of that challenge. Breaking the Wheel and not telling anyone would not serve Eothas in his already moronic plan, Deadfire's "god of wisdom" is a monstrously dangerous imbecile and Durance was right to blow him to smithereens in the first game's backstory.
Setting that monumental writing failure aside, the point stands - Deadfire's main throughline is Eothas breaking the Wheel and the PC plays no part in the unfolding of those events, nor indeed
could they in any capacity. With or without the protagonist's involvement, the exposition for a hypothetical sequel is identical, Eothas manifested as giant rock, waded through the ocean, and broke the recycle bin. The player is presented with no agency in that course of events, nor even the
prospect of agency, and anything they could affect is purely peripheral.
Roping factions in? They help you get to Ukaizo.
Do they? I know the game
pretends that's the case, but the way I recall it, all they do is sail with you through a big storm. Which you can also do on your own. Big whoop.
A failure instead of futility? You can have Wael's titan fight Eothas.
Is that a DLC thing? You'll forgive me if I didn't throw more good money after bad.
Anyway, just go through my TLDR again, I know it's rambling but I did cover it from every angle and whichever way you turn it, Deadfire's critical thread is fucked.
P.S. If any of you actually play Avowed,
do share how exactly it relates its timeline to the events of Deadfire. I guess you don't have to worry about reconciling conflicting player choices for a sequel if you never gave the player any choices in the first place.
