Well said. These qualities, the player's agency with branching paths, choices, and their consequences, are what sets Obsidian's work apart and utilises the unique aspects of the interactive medium.
Also the strong writing and characters, rich lore, and other engaging and well-designed gameplay systems.
I am looking forward to Avowed, even if I am going to wait before purchasing (would like to have it on GOG and complete).
There were Eothas and the faction leaders. I found myself quite enjoying cutting down Atsura and Hazanui Karu. They were reasonably grounded and understandable, while having the capacity to be compelling antagonists. The same can be said about the other factions, I suppose. The Vailian Trading Company was the least directly hostile to the party, but they absolutely could (did) murder random civilians.
On the other hand, allying with a faction would provide a satisfying ending as well. Though, as it required compromising my ego and losing companions, I greatly appreciated the ability to finish the game without their support.
