I seem to recall that the majority of players said that they didn't have enough time to care about the other sibling to have a reaction.
So what is it? What is a significant amount of time to start to care?
Would it really have made a different impact? Would you sacrifice the entire mystery behind what caused the explosion to reenact an irrelevant storyline plot?
The elven inquisitor comes alone to spy. Would a little scavenger hunt before the explosion make you care?
What about DAis focus on the various forms of faith. What about people thinking you are the Herald. The character can have memory loss but you won't,
These are all Questions you are ignoring in favor of adding additional content that would ironically end up lessening the impact of half the storyline.
So no, I disagree. The current method allows a greater freedom for roleplaying your characters origins while plunging you deep into an ice cold lake of wtf is going on. Perfect.
You don't necessarily have to care, but it would have made sense and it would have been appreciable to participate to the conclave, to know the protagonists, to see some faces, and it would have more an impact over absolutely nothing and after the event seeing everyone crying and saying over and over how it is horrible, how the divine was awesome, blah blah blah.
Yes, it could have had an impact, like it had an impact on me with DAO origins. The game felt totally complete from the beginning to the end. All the origins made me feel something before leaving for the grey warden. The current method you are talking about in DA:I didn't really show me that it was more working and better. The story hasn't been better than the previous episodes, and I actually feel that the beginning of the story with my PC in the fade isn't clear at all. I wasn't satisfied at all with the recovered memories revealed and was pretty much meh. Some big holes unexplained to be honest.
Like why the PC is the only one close to the Divine ? Why he was there ? like " hello, is there someone there ? why are you crying ? " How Corypheus acted to blow up the conclave ? Why he needed Justinia exactly , because she's kinda there, like a prisoner, but it is not explained. Why Cassandra and Leliana, right hand and left hand weren't at her side and where were they ? How my PC fell into the fade, and why only with Justinia, but not the grey warden and Cory who were in the same piece ? Where have they gone ?
When you have to imagine so many things about the beginning of the core story, I'm not sure it can be considered as the best thing for me.
The only thing you know for sure, is you are in a dark chamber, you see the bad guy, and you cry, " hello there, what's up " , you succeed to flee from the fade and that's it, with some questions which remain.
I didn't feel that the intro of DA was that great.
