It's hard to think of a series that's more reactive than Dragon Age. While plenty of RPGs react to our decisions in a single game, Dragon Age stretched it over three, as we carried over almost every decision we made in Dragon Age: Origins and Dragon Age 2 into Dragon Age: Inquisition.
However, since there was a console generation between the second and third games, BioWare had to get creative. Thus, the Dragon Age Keep was born. If you connect your account to the site, then it will automatically track your decisions across the series (or, failing that, you can input them all manually). Then, you export the world state to Inquisition, and voilà, the game will now react to all of the choices you've made previously, such as who sits on the Ferelden throne, and whether certain characters are even alive.
We're not counting Dragon Age: The Veilguard here, because the world state import is completely offline, but only accounts for three decisions.
While this worked well at the time, I'm sure you can see the glaring issue with this - it depends on an online service staying... well... online. It's already stopped working in the past without warning,...
