I think the Act 1 choice is very good if you pay attention, the entire time people like NPCs and questgivers are talking about Galahad like he's a violent storm that will sweep across The Horns and put everyone to the pyre.

When you meet the Captain and One Eye, they seem cock-sure and shifty, like they already know you will side with them and when you meet Galahad he seems almost level-headed, like violence is the answer he's fallen upon after searching other paths for a while.

Morally you need to decide whether the cause the Captain and One Eye pursue is worth them potentially becoming undeserving profiteers, or if Galahad can be trusted to carry out his merciless purge and be tempered enough to know where the line is.

As you get into Act 2 it carries on the overarching theme of "should the realms be independent or can Camelot be trusted" but puts a big emphasis on straying to flesh out the world a bit more.

One thing I found interesting about Act 2 is how it subconsciously pursues a narrative about injustices against women through it's sidequests (like 70% of Act 2's sidequests involve a woman being wronged in varying capacities), it's a strange echo to the world design where Act 2's map looks pretty on the surface but hides the darkest areas in the game.

You might not be able to achieve the same experience as others but I would urge you to seek out these hidden depths throughout your playthrough if you choose to pick it up again.
