Aight, so going down the list of those faction conflicts:
Templars vs Mages.
The reason why I really enjoy this one is because both factions are right in their own way. Mages are absolutely treated like shit and are very often subjected to a fate worse than death - to be made a tranquil, aka magical lobotomy. Also such treatment is reinforced by religious dogma. However, this is not without justification. All mages due to the rules of the setting are constantly a threat to others and themselves. Even the most experienced mages, when the situation is wrong in just the right way, or the circumstance forces one to "go all out", will become possessed by demons and cause destruction to all around them. Control is necessary. I quite like that this conflict is presented in the background and isn't shown as an open conflict (at least if you keep DA:O in a vacuum as it should be, because sequels weren't originally planned). This means that the discussion about what should be done should be far less partisan, and I believe it would be really interesting to discuss the possibilities of how such a conflict could be resolved. Also, I think, it is a very interesting portrayal of the policeman issue, so prevalent currently, of what happens when a guardian starts thinking they are the punisher.
Who becomes the king of Ferelden.
This one is slightly less interesting, but would be quite curious to properly dissect all of the many different paths, as they all relate to the rather interesting topic of feudal politics. I don't recall of the top of my head, but I believe there are like 10 outcomes which all have their own hooks.
The best one for last. I partially delayed my reply so I could look this one up better, as I just discovered myself a new curious perspective for the conflict between the two candidates.
Basically the situation, as first seems presented, is this: dwarfs are a collapsing empire that also is ultraconservative and thus suffers for its failed caste system. The two likely royals are - the son of the last king, Bhelen, who presents himself as a social reformist and an old noble conservative Harrowmont, who claims to stand for stability and to be against the other candidate, alleging he murdered his siblings and father to get into power. Obviously first instinct is to support the reformer, however it becomes clear that he is deeply connected to the dwarf mafia and is also in fact killer of his family, while also being a total piece of shit himself, compared to the kind Harrowmont who truly seeks stability. However, what matters is what these would actually accomplish as king. Turns out as how horrible Bhelen is as a person, seeking power for himself he manages to reform the crumbling empire and drag it out of its ultraconservative isolation, while the nice guy Harrowmont manages to fuck the castles dwarfs even more than before while still leaving everything crumbling. And while it is clear for us lefties that Bhelen is based here, it would still be an interesting discussion on gaming forums.
But wait... that is not the full analysis of the dwarf kings. While taking some more research I had a eureka moment. No, Bhelen isn't based, they are both shit, and this conflict is a perfectly predicted parallel of 2020 presidential election. Let me explain. One of the main driving desires for Bhelin is power, that is the only reason he carries out his reforms. He wants to improve the situation for the castles, but mainly only so they could become his cannon fodder to restore the lost dwarf empire. He is the proverbial Trump - leading what remains of the dying empire into a last huzzah charge of the Light Brigade. There is no victory to be gained - the dwarfs got crushed by the darkspawn while their empire was at its zenith, Bhelin is fucking deluded in his quest and will only destroy the remnants faster. Meanwhile Harrowmont is the perfect Biden - a dying old man who is just so nice. It is literally stated in-game that he will die soon. His vision for the future is just a continued collapse under the old normal. Its the same "come on man, don't let that mean guy lead us to ruin, join me and lets all fade away as we always did". In short, dwarfs are fucked one way or the other, but the exploration of this situation, especially when it is presented stripped from IRL politics, can be quite fascinating.
Anyway, that's kind of it, hope I didn't sound too much like an epic redditor in the last paragraph with the 2020 comparison.
