What is wrong with Oblivion? Care to explain?

[Mummelmann]

A few problems:

Too repetetive

Some major and potentially ruining bugs and glitches (feel free to look up or ask for exapmples btw)

Spells are majorly inefficent compared to Morrowind

Level design is unvaried and mostly bland

Balancing issues; monsters level with you, when you play the game you'll realize that this is not only silly; it makes the whole game uneven

Mission/Quest system and general content is exactly like Morrowind, which is both good and bad

Too many powerful items; it is entirely possible to become immune to all forms of damage (no joke)

Frustrating AI; "radiant AI" was debunked after some major issues (PM or post query if you want to know what they were btw) and what came instead is one of the most hampering features of the game. AI is terrible, to sum up.

There are considerably less skills and levels to be had compared to Morrowind

The main story is quite good but way too short, if you dive right in you can skim through the main quests in 10-15 hours which is pathetic for any RPG

Lack of combat system; you hit and get hit, that's basically it. Nothing special to the genre, this is the one and only field in which Dark Messiah has the lot completely beat!

The expansions: Shivering Isles is basically the exact same as the main game only with different characters and different environments (there are a few innovations). Knights of the Nine adds precious little to the total experience, and even getting it started (which entails visiting all the wayshrines) is frustrating (the shrines are very hard to find sometimes).

Conclusion: I love Oblivion, but having spent 300-400 hours playing it I am painstakingly aware of its faults and flaws.
