I'm going to say it.
Dragon Age should just have had a demon invasion on each game until it was the final archdemon.
This seems like an overused trope, but it is a trope for one reason : it works in video games. And it has been labelled such an overused trope it is hardly used anymore because it feels dumb. But it's not dumb. If you are of dubious morality and have immense power at your disposal, you invade . For no other reason that you can. Look at world history.
People watched GoT for the political drama but the real questions everyone was wondering was when the White Walkers would attack.
And if it feels repetitive, change the way it unfolds, change the part in the world, change the characters, change what's at stake. You can do a lot with such a simple preset.
Instead they went with political stories, treacheries, hidden agendas, etc etc but it doesn't work. They write convoluted shit that is dumb and fail to involve.
Bring back the demon invasions if you want to save D.A
