130 dungeons is a GOOD thing. For two reasons.
1) They are more unique because of it. I'd say very very unique.
2) The world won't feel as cramped up as with Oblivion which had over 200 dungeons. The world feeling cramped up is a horrible feeling. Almost wherever you went in Oblivion, there was a dungeon like 20-30 secs away from you. That svcked very much.
The world size is approximately the same as Oblivion, perhaps even smaller, which is pretty bad I'd say. I'd much much more prefer the world being double the size of Oblivion, and then have locations and such more spread out.
Anyway, not much you can do about that now... so it's a good thing there are only 130 dungeons. A very good thing.
Agree. We don't really need 200 dungeons anyway. I gladly have a smaller amount of dungeons if that means they are more unique.
And the second point is valid as well. Just walk though a forest in a straight line in Oblivion, and you "discover" a dungeon every minute. The map is crammed with them, they're not hidden at all, so the amounts of dungeons is just annoying. With Skyrim being around the same size as Oblivion and with almost half the amount of dungeons, I'm sure the world will feel much more realistic without a dungeon in the open every 100 meters.
Seriously, I would have been satisfied with 50 dungeons if they're all unique and filled with various traps, enemies and loot.
Add the fact that they've said they have more traps and puzzles, and the fewer dungeons of Skyrim is going to kick Oblivion's dungeons butts.
