I can live with this if the setting and plot make it so just travelling around doesn't seem very credible, RP-wise. In BG2 the party is getting to a level where it isn't too likely that they're just going to stumble onto something worthy of their attention.
I'm not saying that there should be whole extra zones filled with level-appropriate content. I'm saying that the zones shouldn't be gated behind a quest-giver. De'Arnise Hold should always be there, regardless of whether we've been told about it.
But I take your point that there is a whole world there which we're mostly ignoring because it's beneath us. I hadn't really considered that. And given that, places like De'Arnise Hold will be (from the PC's point of view) part of that world we're ignoring, unless we have reason not to ignore it.
That's the best defense of BG2's design I've seen. Well done.
I still prefer discovering content on my own rather than being directed to it (which is why I don't complain about the quests in DAI or Skyrim - I'm not doing the quests, I'm just exploring), I now recognize that BG2's design does make some sense.
(Lampshaded in ToB, come to think of it.)
I never did play that. I never really got into BG2 (I never finished chapter 2).
And in KotOR the war is ongoing, and you know which planets have a piece of the Star Forge map.
But on those planets, there should be some areas which have nothing to do with the Star Forge or your quest for it. Tatooine consists of 4 zones: the city, the desert outside the city, the sandpeople settlement, and the bantha herds. You have to visit all of them to find the star forge map. I'd like to see two other zones that were entirely optional.
Korriban actually did have some optional content. And such content would be hard to justify on Manaan, but you take my point. I want the game world to exist independently of my quest.
ME1 has a different problem, since the UNC misions are there but the plot critical leads get dumped in Shepard's lap right away. And not very credibly-- after all these years, I still have no idea who reported geth on Noveria.
I struggle to find any redeeming features in the whole ME series.
