I didn't find DA:O that engaging. Couldn't care less for grand majority of the characters, only the Warden and Morrigan were interesting at all, and it's not surprising in case of the Warden, since you shape him/her yourself. DA:O has nothing on Mass Effects and KotORs. Forcing Zaalbar to kill Mission was just brutal. Tali's suicide in ME3 was heart-breaking, as was Mordin's death. HK-47 was the funniest character in any game ever, the only one that comes remotely close is sergeant Dornan from Fallout 2, I guess. The list goes on.
