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 iPost too long. Click here to view the full text.
