dtgreene: More OOB stuff, this time in the sewers.
Bass47: Is the game good? I ask because I want to play a TES game and I don't know which one.
I would say that all the TES games are good, but they also all have serious flaws.
Oblivion is probably the most balanced of the games available here, but, in making the game more balanced, they took away some options from the player. (No custom cast-on-use enchantments, no levitation, for example.) Another thing that many players have complained about is the level scaling; as you level up, so does the rest of the world. (That's actually true throughout the entire series, but it's less true in Morrowind, which many Oblivion players played first.)
Also, the games aren't always the best at checking collision with the ground; prior to taking that screenshot, I hadn't used any cheats. (I had to disable collision to get out of this.) This problem is present throughout the series, with Daggerfall being particularly infamous for throwing casual players out of bounds. The only games in the series where the ground is as solid as it should be are Arena and Battlespire, and even then it's possible to go out of bounds in these two games (and in Arena, doing so can cause a crash or softlock).
One thing I like about Oblivion is that the enemies and treasures in dungeons respawn. In Morrowind, by contrast, only creatures (not humanoids) respawn, and random treasure in dungeons does not.
