4 Over-priced but worthwhileAzeryk | 20/05/2007 | See all Azeryk's reviews (56)Top 100 Games Reviewer Knights of the Nine is an expansion pack to the award winning game The Elder Scrolls : Oblivion. Not really being an expansion pack as such, it's more a colaberation of add-ons to the main game. It adds new quests, weapons, armours and spells to the already huge main game helping to extend it's playability by 5-10 hours, depending on how fast you play.The only downside to this pack is that you most likely won't use all of the content, this is because some are designed for certain types of character. For example a fighter won't ever need the Wizards Tower, Vile Lair and is unlikely to use Spell Tomes. This is why downloading this content from their website can work out cheaper.However, the parts you will use are enjoyable and the main quest in the expansion is good to play and will add more if you loved the main game. Slightly over-priced but worthwhile.
