The Knights of the Nine CD collection is an excellent addition to anyone's Oblivion game. There are a few subtle gameplay tweaks (such as the Spell Tomes), while others are great quest addons (such as Mehrune's Razor), and the Knights of the Nine itself is a wonderful added faction with a compelling storyline. I would recommend anyone considering downloading the addons to Oblivion to instead simply buy this disc--there is none of the hassle of Bethesda's registering process--which doesn't work on many computers without tweaking, and which doesn't work on Windows Vista at all. There is also no restriction for installing or reinstalling this software as many times as you like on your computer, which is a great bonus for me. After switching from Desktop to Laptop, having some installation/activation issues and getting a new hard drive, it was going to be impossible for me to activate the DLC's I already owned, so I instead opted to simply buy this CD. I definitely don't regret it.

This is an add-on to Oblivion. It adds only a few hours of game play, but is interesting and somewhat fresh. I paid full price when it first came out though, so wish I would have waited for discount. Other than that, if you are a fan of Oblivion, this is a must have.

The good thing about Knights of the Nine is that it keeps you in the Oblivion world you are familiar with. I particularly like the world of Tamriel and didn't much care for leaving to go to Shivering Isle to pursue the quests in the other expansion pack.

Knights should have given us far more armor and weapons. The new selection of items to acquire really isn't anything greater than what was already in play. I'm at level 35, so I can pretty much run around stark naked and just blast NPCs with spells. It would have been nice to encounter tougher enemies and more weapons, spells and armor, at least for variety's sake. I slaughtered my horse ages ago. Who needs it when you can teleport everywhere? So, the horse armor looks cool, but it's basically useless because horses are useless in the game.

Ultimately, it is still a pleasure to play. Not a terribly deep expansion pack, but I picked it up for $9 and got a few good hours of fun out of it. I would recommend it.

I decided to get the combination with all the downloads because from Amazon it was cheaper than getting direct from their website. Some of the add-on's are pretty hokey like the horse armor. Not sure that is worth it except if you like the graphic apearance. I haven't gone through the Knights of the Nine portion yet. That will wait for a later point in the game as it is its own quest on top of the ones you get in the game. I love the wizards tower. That is a must for anyone playing a spellcaster of any sort.

I'm going to shock everyone. I don't like it. Why? The game doesn't save. I have trouble with all the different keys. Oh, and I keep getting killed.
I was really hoping to give it a good review, but atlas, I can't.
