While I have been a proponent of Skyrim’s exploration feeling very different, very much more “sandbox” in a way than that of W3 (though I’m really not far enough through W3 to make definitive statements) I do disagree with the concept that turning the question marks off in W3 somehow is “cheating.” The option is there in the official options, just as various difficulty options are there, etc. I actually, on my second play through in Skyrim, used a mod to turn off the POI markers on the compass and it improved the experience for me; that certainly was not an option provided by the developers.
If you keep the question markers on, the difference in exploration is, in my opinion, huge. There will be no real surprise when you run across something, because you are specifically going to that marker on the map and you KNOW something is there, just not what it is. It would be as if every POI on the map in Skyrim was revealed from day one. Even with the markers on the compass on, you still don’t know until you get close whether there is something on the other side of that hill. So yeah, with the question marks on, it is a very different experience.
I get, I think, where the comments are coming from about a big announcement and horns blowing when you run into a minor POI in W3. If you spy a shack in Skyrim, and you wander into it, find some interesting clues about what happened here, dig around and figure out more, find a hidden chest with something appropriate in it, there’s no big proclamation on the game screen that you just completed XXX. You just quietly wandered in and found it. No one else in the world knows you did. It was a remote lost place that you somehow accidentally discovered. It is indeed hard to articulate, but it doesn’t feel as “gamey” as it would if a big announcement popped up on the screen proclaiming “YOU JUST FOUND THE FORGOTTEN WIDOW’S CABIN!” and then “YOU JUST COMPLETED THE FORGOTTEN WIDOWS QUEST!” Perhaps that what someone meant when they said the exploration in Skyrim felt more “organic” - it was there, you stumbled into it, there’s no game system congratulations. It results in some “quiet moment” type of exploration that you don’t get in W3, where you find a dead guy in the shallows and get a big game announcement, 30 seconds later find his chest in the water right next to him and get another gamey congratulations. I’d much prefer no announcements popping up giving me some kind of “score” or credit for that.
The other piece I will have to discover is the density of discovery in W3, with the ?s turned off. The map of Skyrim with all the POIs revealed shows a world extremely dense in POIs. Which is why I could play all the way through, walk every inch of the map, and my brother do the same and yet we both would describe things to each other afterwards the other never saw.
But again, as small a thing as it is, I do think (with the ? turned off in W3) one thing that makes the exploration feel very different is the way W3 is more “gamey” feeling on many of the “little” discoveries.
Does that make Skyrim a better game? Nope. I will continue to proclaim the two are very different games by design. ;)
