i didn't play an origin other than durge or tav for long but what i played gave me the same impression. some differences and unique stuff but overall same experience as a tav and same choices for the vast majority of the game

i did a ton of reloading to see branching options between my different playthroughs (did like 500 hours of this game) and idk man i feel while you're not wrong about different playthroughs offering different content i also think the vast majority of it is the illusion of choice and differences. sure there are thousands of tiny differences that might influence someone to lean one way or another with a portrayal but they're all very tiny and the foundation should be the same for most, biggest differences should come from how their personal quests end
