Anyways, no. A empty light/darkness system would take me out of my immersion. It was useless in BG1+2.)
We'll have to disagree here. Strongly.
It set up a lot of stuff in BG 1 and 2.
Unique monster/enemy encounters that happened only at night (or more rarely only during the day), questlines that could be progressed/completed only in certain time windows, etc.
Not to mention the NOT negligible impact it had on the whole atmosphere, anyway.
We already talked about this extensively, but it's hard to overstate what a FUCKING BUMMER it will be to have the city of Baldur's Gate perpetually frozen in an eternal noon, as the rest of the world is right now in EA.
No walking for the city' streets at night, not making unsavory encounters in its dark alleys, no city lights turning out one by one at dusk, etc, etc, etc.
I do not understand your dislike for origins. I had no use for them, and still don't, but all they do is to allow you to play a companion instead. Since the character exist regardless of him or her being a playable character, I also rather doubt it is that expensive to create them.
And I do not see how they damage immersion, if you see the problem there, please tell me. (Since it is a bit offtopic, just send me your opinion or links to your statements instead, if you prefer..)
No, what they actually do is expect from the game to rewrite (and often re-voice) a lot of redundant stuff from multiple perspectives.
It's a lot of time and I money I would have loved to see spent elsewhere for a feature that is almost quintessentially redundant. I wonder how many people played BG2 and thought "Wow, if only I could replay this entire thing, but as Viconia".
