im not a huge fan of the origin character approach for alot of the reasons others have mentioned here, but mainly i feel like a players custom character (which i would also argue is the 'classic' dnd/BG choice v dev written pcs) currently feels underwhelming/underwritten compared to the origin characters who all have their own narrative/story and unique story driven mechanics, in addition to the shared tadpole plot - that apparently isnt all that special as it appears fairly easy to pick up given the number of other true souls you run into
ive posted this before, but as ive played through there is nothing that makes me feel that my custom pc is integral to the bg3 plot, to the point where i feel like if your custom pc never survived the ship crash in the tutorial the whole story of bg3 would still be able to continue on regardless
