Man, I know it's entirely subjective, but Oblivion isn't anywhere remotely close to Morrowind's league. It basically went so many steps backwards. It's not like the worst game ever or anything like that at all, but I wasted so much time (seriously almost 100 hours) with it trying to find
something to like about it. The only thing that I can honestly say that I really enjoyed was the Mage, Thief and Dark Brotherhood quests. I also read every text I found, but they were boring as shit compared to Morrowind.
The dungeons were actually kind of cool at first, but then you soon realize that there were literally three types of dungeons with very little variation, and so going far to some nondescript location in search of adventure (i.e. a "scary dungeon" just led to more of the same. Even the vampires were dull.
Then you have the actual gameplay mechanics of the game; some of the worst I've ever played, and I'd rather play a menu based RPG over that crap.
-Level scaling, with leveling loot that was just awful.
-One of the most horribly convoluted and unintuitive leveling schemes (Morrowind is similar in that respect though) imaginable, that actually works against your supposed "class".
-Shitty stealth. You go from it being bad, to you being completely broken to the point where you may as well just have Golden Gun mode on with invincibility.
-Boring NPCs. There were a few that made me laugh, and maybe one I remotely cared about at all. The rest were just dull, dull, dull, dull.
-Shitty combat. Yeah, the year is 2006 and we still have some steallar Doom/Hexen combat happening. The game was an FPS trying to disguise itself as an RPG. The most used method to fight? Backpedaling.
-Shitty spell system. It's just like Stealth; it goes from awful, to mega-retardedly strong, especially after you can start making customs.
People went goo-goo-ga-ga when it first arrived in 2006, because the 360 was new and Oblivion had some of the best graphics a console had ever seen. And it played like a tech demo too.
Sorry for crapping all over something some of you enjoy, but I seriously cannot stand that game at all. It's about a mind-numbing of an experience as I've ever had with any game and just can't understand how Bethesda thought it was a great idea. No amount of graphics can make up for abysmal gameplay mechanics, boring dungeons, boring characters and a boring story.
I actually kind of envy those that can stand to play it.
