Oblivion looks gorgeous but plays horribly and sounds atrocious. The thousands of lines of character dialogue are a grating and boring pain, delivered by a very few uninspired voice actors who play hundreds of different characters. All characters you meet invariably speak in a deadpan monotone, which just adds to the "where am I" feeling you get (it's very very easy to get lost in Oblivion because so many places look and sound the same). Your interaction options with NPCs are limited to grunting out single words - a norm for consoles perhaps, but a royal embarrassment for a PC game.
After you've played the game for about 2-3 hours you will have been exposed to everything this title has to offer. Although the wilderness is beautifully done, most indoor environments are very similar to each other - some are even identical (again, making you lose track of where you are). Combat is somewhat interesting because it incorporates specific melee moves (e.g., left +click or diagonal + click to perform different strikes) but this is not enough to make the game memorable. Spells are a big let down: the highest level fireball you can obtain looks and sounds the same as the beginning level flare attack (i.e. unimpressive).
The storyline never really comes to the fore, never builds any tension or suspense. You may take a trip to a specific city and close a specific Oblivion Gate (an experience that is interesting the first time but becomes increasingly dreary as you repeat it ad nauseam). Maybe you will be involved in a group based skirmish with some NPC allies, which you will curse and hate because they always get in front of every single attack you aim at the enemy, and that will be the highlight of your trip. There's very little else.
In terms of the engine, the game is almost unplayable without mods. The GUI is lifted straight from the console version of the game, meaning you have very large clunky windows that show very little information but take up most of the screen real estate. Different screens for character stats, skills, inventory, spells, and effects only complicate things by making information as difficult to correlate and navigate as possible. Fortunately there are quite a few mods that can help (but never wholly fix) these grave shortcomings.
Crafting is unnecessarily complicated. To give you an idea, alchemy requires you to collect hundreds of different components and then combine them. How to combine them is not clear (unless you use a mod). Since you're dealing with combinations of different classes of ingredients it would make sense to use multiple windows for your arcane dabblings, but instead you are limited to going backwards and forwards between single screens of uninformative and lengthy lists of plant names.
In terms of combat and progression, it doesn't matter what level or skill you are, because (as others have said) the game scales every encounter to your level, removing both the challenge of the game and also the "pwnage" satisfaction of demolishing your opponents through overwhelming brutality or magical cunning or what have you.
Really, apart from the environment graphics (which are extremely good) I found this game soporific. I still boggle at how highly this game scored in many game reviews. It is perhaps acceptable as a console RPG, perhaps even innovative in some ways, but PC users have had access to better for several years (excepting graphics of course).
Comparison to Neverwinter Nights - though the two games are very different - is swift and brutal. NWN has heaps of story and content, dialogue that involves more than a single word and a single choice, a myriad exciting particle effects, radically different foes and NPCs, countless items, skills, and spells that actually make a difference, etc.
As an FPS-RPG hybrid in my opinion Oblivion fails miserably, whereas Neverwinter is a pretty good isometric RPG.
