I was thinking that a Ameridan's story could be a setting of a great rpg. He's a character of curious background, has a smashing profession/hobby to match, an interesting roster of company/close friends and he was a rather detrimental character in Thedas' history.
His story in the canon is pretty settled, however, so why not go non-canon and give players the power to steer the story's direction where they can make a small difference, go for an entirely different conclusion, or even try to replicate the canon.
Maybe for a change, instead of having a large roster of possible companion, Ameridan's companion should be limited to the three people we get to know in JoH, but their gameplay facets and narrative-affecting factor should be proportionately huge and deep; perhaps instead of applying the traditional system, these 4 characters will have unique selection of ability trees that players must consider carefully, and wether they fight up-close or at range is not strictly limited by their Class, nor do the weapons they can wield follow traditional rules (eg. Heron can use the bow despite being a warrior, filling the role as Templar Archer. Ameridan being a mage can actually use his staff as an effective melee weapon). Ameridan being the central character and having the least defined ability school might be able to pick a specialization.
As for how companion is affected by your choice in the story, I say maybe they can work around and expand beyond that; companions not only react to your choices, but their outlook and fate can be affected by the smallest thing. Some examples: Orinna might not be able to perform certain things or come with into some areas due to her inclination to follow tradition, which players can change through choosing the right options at key points in the story. Bringing Telana into too many demon or abomination fights will wear on her and possibly permanently remove her from the party if handled wrong. Choosing the Blood Magic specialization for Ameridan will open up possibility of an entirely different ending, but inevitably put Ameridan at odds with Heron and cut off the chance of happily fulfilling Romance with Telana. Choosing the Spirit Healer specialization will give the players option to prevent deaths that are otherwise scripted, granting immediate benefits but also having unforeseen ramifications later.
So, what do you guys think?
