But there's so little exploration of the Elven deities.
Only because it's a very minor faith in Fereldan. Only the Dalish elves follow it. The game mentions numerous times that the Dalish are small in number and have forgotten most of their heritage and culture (including their religion) over time.
The problem I have is how much monotheism is pushed. "The Maker." "So let it be." "Don't lose your faith now!" "It's our duty to educate the ignorant." "Maker bless you." ...Not to mention the incantations. Do they mention elves? No, only in the "dissonant verses."
I seriously think you are way overreacting to this. I am a hardcore atheist, and I do not at all feel that the devs are 'pushing' monotheism on us. Yeah, most of the people of Fereldan believe in the Chantry, so you hear a lot of "Maker this" and "Maker that" in the game. But that's because it's the dominant faith. Sten of the Qunari has his own faith and references it often. When you speak with the dwarves, they generally say things like "By the stone!" and "May the ancestors watch over you" instead. Dalish elves say things like "Creators be with you" and such.
Dragon Age is NOT based on the real middle ages, although it's clear it's heavily influenced by it. But if it WERE based on the real middle ages, would you not expect most of the average citizens to be Christian?
Besides which, at no point in the game is any real evidence shown that the Maker is even real. I have encountered numerous debates online on this. Some think the Maker is just a very powerful Fade spirit. Some think Andraste was just a mage. If the devs were really trying to 'force' the view of monotheism on us, the Maker would most definitely be real and he would play a pivotal role in the game.
As for the companies that put out NWN & Dragon Age: Both are Bioware products.
NWN 1 was made by Bioware. You keep referencing the second game specifically, which was made by Obsidian. The upcoming third game is going to be made by Cryptic.
Another problem I have with this game is that there's no reason whatsoever why our hero(ine) should be the leader of the gang. If anyone should be leader it should be Alistair. But since only our character can be leader: a reason for this should have been established from the beginning. This was done very well in NwN2. It was not done in DA:O.
Actually, there is. Alistair even points out he is not comfortable leading, and this becomes a big plot point later on when you find out about his past. (And if you've been to Redcliffe Village, you should all ready know that, assuming he was in your party at the time).
Like I've said before: Perhaps the comparison between the two games is unfair to an extent, but again: the reason I make the comparison is that NwN2 was the last fantasy RPG they made. So it's only natural that one see DA:O as the sequel.
Again, Bioware did not make NWN2. The last RPG they made before Dragon Age was Mass Effect in 2007 (Dragon Age came out in 2009). Knights of the Old Republic was before that in 2003.
In truth, Dragon Age is often referred to by Bioware as being the spiritual successor of Baldur's Gate, not Neverwinter. So if you want to make direct comparisons, it seems BG is what they were going for, not NWN.
Every time I saw monotheism in RPGs, it was always some bad guy plot or inquisition like.
He's right. In just about any JRPG that has monotheism, it's generally shown as pure evil. Not just the god itself, but usually all of its clerics, as well. Take Final Fantasy Tactics, Final Fantasy 10, or just about any of the Breath of Fire games. The fact that the Maker is not the final boss in Dragon Age and the people of the Chantry are shown to have both good and bad within them was kind of refreshing, in my opinion.
