Please Implement the Dragon Age Keep in future games.

I think the problem with the Keep is that it's an online service, so if some day in the future the service were to end, Inquisition would lose its import system and you'll be limited to default world states. Ideally I'd hope for an offline solution, preferably embedded within the game, but a lot more robust than what Veilguard had. 

I agree. An offline solution would be most suited. 

As soon as I booted it up for the first time, my mind went to Dragon Age Keep. haha I would imagine they didn't have the time, budget, labor, or go ahead to turn this into Baldur's Gate 3. That and not too many items would carry over to this scenario without ballooning the game in general. Hawke, Sandal, Iron Bull, Cole, Tallis, non-statue Valta, Fenris, Sebastian, Bethany or Carver, Zevran, The Warden, Alistair, would all have had large to not so insignificant roles in this game. That is just off of the top of my head. Though to be fair, Inquisition managed to implement enough of your previous choices to make a decent personalized campaign.
