Ugh, there's no real choice in BG 1. You are CHARNAME, adopted child of deadguy, stepsibling of Imoen and are gonna do the Bhaalspawn story arc. I don't get why people buy a video game then bitch about it sending you on its story. There's stuff you can do in tabletop that simply wont work in the video game medium, and an open sandbox is one of them.
This is very true.
But I would have to say sometimes the dialogue lines don't really seem to matter.
No matter what option I take the voice acted line is the same.
For example talking to Shadowheart about her religion as a selunite. Sharan or something else.
Maybe one unique line here or there at most and suddenly its the same exact dialogue lines.
You would think Shadowheart would he vehement against me for being a Selunite... but barely a reaction really.
