Granted most of it were cameos, but it was cool nonetheless to see Loghain appear in Inquistion for example.
Loghain was not just a cameo, he had an extended presence in a major story questline, along with Hawke. The sort of presence that could be rapelaced with someone else, but still. Alastair was a cameo... or maybe that's just because of my worldstate that made him the king, instead of a gay ward-
Why am I defending Cisquisition? Has it come to this?
Come on, it was a good example of different worldstates.
It could be Alistair, Loghain or the default guy. Three actors recording a decent amount of lines (with some variation)
Aaand if you did the main quests in a specific order, you could catch additional scenes of Alistair/Loghain and Morrigan. Aaaaand they could be talking about Warden/Alistair/Loghain's son.
If you didn't import a suitable save, you wouldn't see all this possible content.
Even if it doesn't impact the main story at all, it was still great on Bioware's part to spend time and money on those possibilities. Something to be proud of, I ain't ever gonna deny them that.
