Two Worlds. It's an attempt to take a gameworld bigger than Oblivion and some more hardcore aspects of ARPGS and mix them together. They don't even do this right. While enemies don't scale, most of them can be beaten by luring them to a health shrine which heals you whenever you're damaged; and just hacking away, making this even easier than Oblivion. The voice-acting is far more varied than Oblivion's and also far cheesier. When your character (who can only be a human male with a VERY limited set of facial features) kills a chicken and says "Say hello to Death!", you'll probably be on the floor laughing and in tears.
Considering the sheer size of this world, there are relatively few dungeons. Whereas Oblivion had somewhere in the number of 300 or so dungeons, this one has about 60, and then a few outdoor caves and enemy forts. And several hundred campsites of three bandits and a chest. Some of the chests at said camps don't even open. Horses are so poorly done that I at one point was leaning about 20 degrees from the ground, which was already at an incline, on a horse. Enemies frequently die and fall through the geometry, or stay in battle positions like statues of war. Citizens have pretty much the same response to everything in a given village. The map just sucks, quests will often give no hint whatsoever as to where you have to go (the ones where you have to find people and kill them). Entire quest lines can be skipped by doing things in the wrong order (this doesn't mean they were branching quest lines, this means that a quest line was inaccessible after completing a completely unrelated quest line). It is even possible to break the story quest line. People you have to meet for sidequests might just decide that they don't exist. You can go to their house and wait and wait and wait and nothing will happen. Quests can be solved before they're even started.
Like Oblivion and Morrowind, this game relies on cells to load areas, and lets you know when you're loading them. But just as often, there will be an unexplained hang-up of about 5 seconds. Frame rates are inconsistent, it looks awful on standard definition TVs (you can't read the damn words because they're too tiny and serif-ized). Enemy variety is almost non-existent. I made it to level 32 fighting Orcs, Goblins, Wolves, Bears, Boars, and a couple Ogres. And boatloads of shirtless bandits. It's surprisingly easy to get over insurpassable mountains and find yourself in an area the developer clearly had not planned on anybody visiting.
The whole thing is just one big fucking mess. I would bet money on the developers not hiring ANY QA testers whatsoever. Atari 2600 games had fewer bugs than this, it's just ridiculous. It has every one in the book short of deleting the root directory on uninstall.
That being said, there were two good things about the game: the Alchemy/Weapon system, and the variety of locales. The rest of the game was pretty much canned scabs in a broth of diarrhea.
