not diffrent just to play out diffrent instend of softy save the world and dance in the rainbow sunline like pixies ... things can play out that way in fact all of that can be the same for people who truely want that softcoreness that has no depth whatsoever thats cool if it was for you... there are many methods that wouldn't require anything to change but would open up more depth and the most they would have to do is write in 1 extra scene for those who choice to drop the savior bs and be a spy for them then nothing would really have to change outside of them poping up telling you that X thing request you get it and you tell them until the last expansion/last patch then the work of your spyness and lies to the scions shows up
What "I want" (this is a personal view so don't make it more than it is) for once a game company not enforce this morality code that they believe in.
For example what it boils down to is do you morally believe anything justifys the method. Some people might say no but I personally and i'm sure others say yes sometimes 100s of things must end to restore something true.
which that shows in Wow that they using it to enforce this set moral code with there story. Now in this game it feels a bit dismissel than anything...
Its like well X character with X reason doesn't matter because we believe morally that the ends do not justify the means thus we cant allow this character to do what they honestly have the right to do.
Now for the wow example the issue is they put in a false choice not that they put a choice in...
WoWs issue is it gave you a choice to follow her but it didn't allow you because the company wants to enforce their morality that her methods and her path is immoral thus they can't allow it because it might influence the players to think for themself not to what people tell them.
Instend they forced you into 2 factions that are both weak willed and softcored trashy factions honestly ... and that honestly is why I've always hated wow they had a option to allow dks to follow Arthas and the scourge didn't use it and then they repeated it with sylvanas.
You mention single players but honestly what companys do the moral decision games any more are first-person shooters or sci-fi neither of which are really that great to do it in.
Really the only game that does it is DnD fully and it works great...
Now this wouldn't be fundamentally diffrent it would just throw in a option to walk the path that characters like Emet open to you or help Gaius take over the savages of Eorzea and bring order what would be so bad about that other than "we don't want it empire bad we good free wild lands" really also Nidhogg would have just most likely wiped out ishgard and returned ... also Zenos could have been agreed upon similar to DBz Goku/vegeta thing with fighters just having random disagreements and beating each other up randomly through out the story just for the kicks.
