Eh? Where are these villages and lands getting decimated? There are places that are already decimated when you get there, but that's hardly "change". And what have things like main plot advancement and visions of the future got to do with anything? I'm talking about the fact that nothing in in the Hinterlands ever changes no matter how long you leave it to change. I'm talking about the fact that there are no consequences to your decisions to prioritise other things over closing rifts (or indeed anything. Decide to go close rifts instead of, say, helping that guy get the medicine for his wife, what happens? Oh, right nothing, he's still waiting there for ever - The only time that chosing to prioritise one thing actually has an impact on others is In Hushed Whipsers vs Champions of the Just.). The same applies across the game. The world is unchanging barring when you chose to advance it through main plot quests, and even that has no real impact on things in the various parts of the world. they're still sitting there exactly as they were when you first found them. Those rifts will continue siting there doing nothing.
DA:I gave us a static snapshot of a world. And that is it's greatest flaw.
The Lion seemed to be later in the game than my time spent in the Hinterlands. Perhaps it was because it was later in time.
In the Hinterlands, Towers were built, people were saved, Agents recruited, and a War is brought to near end over time.
But if placing the game on a timer is what would make it a better experience, then make a mod; certainly do not want it for my version. And almost any game with quests is unchanging until the Questee meets the Qusestor; am fine with it myself, but I prefer RP over meta-game philosophy.
And DAI seems to be quite the success at doing this.
