i'm betting it will end up being lots of choices that in the end amount to very little differences in the overall plot. Then, at the VERY end, we'll have a choice to make.
It depends on what do you see as "little differences" ...
Speaking for myself i was quite mad when i found out that in Dragon Age Inquisition ... one specific character returned, even tho part of her story was the fact that she died in Origins ...
And that character even tells you about it ... she specificly sais "i was dead for a while, but then return" just like that. :-/
Where have i seen such lazy writing i ask myself looking at Darth Sidious.
This is what i call "very little difference" ... or to be more precise, none at all.
But when you for example kill Zevlor, there is allready prepared another NPC that takes his place ...
I hope you dont mean such things to be also "very little difference" ... since such change seem natural to me.
And personaly i would welcome more of this.
