While previous games in the series have allowed for players' choices, just three from Dragon Age: Inquisition will carry over to The Veilguard. If you never played that game, don't worry; the "Adventurer's Past" feature in character creation will allow you to set the scene quickly. Vague ending spoilers for Dragon Age: Inquisition to follow!
According to an article from IGN (thanks, GamesRadar+), players will be able to "select a few story decisions via Tarot cards". The critical questions The Veilguard asks are whether you chose to disband the Inquisition, decided to save Solas, and perhaps most importantly of all, who your Inquisitor was romantically involved with.
While this is a relatively small list of continuations by the standards of BioWare's previous efforts, that's apparently because the developer would rather ignore your choices than undo them. The Veilguard takes place in Northern Thedas, allowing new audiences to be tempted with a fresh jumping-on point, far away from Ferelden and all the baggage of previous games.
