It's unreal how fucking boring and awful Skyrim's dungeon and location designs are. It's basically the same shit as Oblivion only even more boring and linear. There's basically no variety and everything is a straight line. It is interesting to compare it to Fallout 4 which is full of cool dungeons and locations. Most locations have full vertical gameplay and several ways to progress, even a random raider camp has several vantage points that can be used by you or enemies. Not to mention that even vanilla AI and enemy variety are pretty good let alone modded one
