Agreement, with caveats:Johnny Novgorod said:Sewers and underwater levels, hands down.
-Not just sewers, but really any tight tunnels/corridors with an abundance of 90-degree angles. I hate navigating these especially in 3rd-person games where the camera gets hung up on the walls. Mazes are no fun. Mazes with enemies, especially fast-moving or exceptionally deadly ones (looking at you, The Depths in Dark Souls 1 and a good third of Amnesia), completely suck.
-Underwater levels where your movement is actively hampered. I get that's usually the reason to HAVE a flooded level but I don't like it. Super Mario Galaxy/2 had a kind of fun way of getting around using Koopa Shells for locomotion, and honestly I loved the way Zora Link controlled in the original version of Majora's Mask (it's to my understanding they slowed you down a LOT in the 3DS port). A water level with natural controls is something we sorely need.
Additionally:
-Super tired of all the tombs in Skyrim. They all look the same, they all have the same enemies, they all loop conveniently back on themselves with a secret door. I GET IT. They're boring.
<spoiler=long digression on this>This is one reason I prefer the dungeon-crawling in Oblivion (minus the dungeons actually ON the plane of Oblivion). There are only 4 or so types of locations (mines, caves, forts, Aeyleid ruins), but there are way more types of enemy sets (bandits, marauders [which yes, are separate classes], conjurers, monsters, animals, vampires, undead [which vary a lot], necromancers) AND these sets are mixed and matched between locations, rather than Skyrim's system of caves being ONLY animals, ruins being ONLY draugr or constructs, mines being ONLY bandits (you'll find necromancers or vampires sometimes if you're lucky). Granted, Skyrim had more types of overworld enemies, but they're all mostly humanoid with different sets of gear.
-Magma caves are never usually exciting either, I can't say I hate them but they're usually just boring. The most interesting "lava level" in my memory was Mt. LavaLava in Paper Mario, mainly because that level had a lot of verticality and some kickin' background music.
