For future readers looking for more to explore, a couple more areas in Act 1 that have significant choices, albeit not for the main plot line:
1. the hag, the sheep, the redcaps, Mariyna, the hidden lair, the husband. There are a lot of options and some very fun alternate resolutions. Very much worth save scumming to explore them.
2. the Missing Shipment, Zarys quest line.
I can see the Hag line and the shipment going into some further affects once we can get to Baldurs Gate proper. Mariyna's brothers say they are from a farm near BG and Ethel's letter to M seems like a hag near there. Additionally I would expect to see the Tiefs in BG if you took that path and some opening of options in that area. Those would all be minor branches though.
