I would hate a tragic Ending.
Why would I hate a tragic Ending?
Because there are so many tragic Endings nowadays. Fiction has become increasingly dark and tragic over the past few Years, doubtlessly in Parts thanks to the massive Popularity of darker Stories (like, to cite a very well done Example, the dark Knight OR to cite an overdone Example, Game of Thrones). It seems, that Darkness, Cynicism and Tragedy is increasingly interpreted as "realistic", which paints a rather grim Picture of how many People perceive Reality. Because, Reality is at least nuanced and has just as much bright Spots as there are dark Spots, just as much Things that inspire Idealism as there are Catalists for Cynicism. And at this Point, coming off a Season of Game of Thrones where their need for Darkness made their Storytelling atrocious, I'm absolutely fed up with Tragedy, Cynicism and Darkness, be they forced or not.
I liked DA:I's in any Way unambigously happy Ending. That's because I like happy Endings and am able to acknowledge that even in Reality, sometimes the good Guys really do win unambigously. In the most violent War of History, the good Guys won unambigously and there was no Doubt about who were the good Guys.
And I want at least the Possibility for an unambigously good Ending in any Game I play. I don't care if you make me work hard for it, make it difficult to attain, that's okay. But give me an Ending, where I feel good. Where I feel happy. Because that's why I experience a Story. I don't do that because I want to get "The World is a bad Place" shoved in my Face.
