This is the best RPG in years and should be purchased regardless of whether or not you are a fan of the series.
Graphics: The graphics in this game are amazing, some of the best to date. Unfortunately, graphics this good require great computers. If you do not have a nice video card you will most likely experience lagging. I used an Nvidia 6800 128 mb card and it runs great.
Gameplay: Oblivion offers a unque combat system that is both fun and easy and allows you to quickly access spells and weapons. The Level system is good to. At normal difficulty it is pretty hard to level up so if you are a beginner I reccomend you lower the difficulty level. I have been playing it at a little above medium difficulty and I have been finding it easy enough to finish most of my quests. Lockpicking is also fun and not that difficult which makes it easy to steal from peoples houses or even kill them if you want to. I have found that the best weapons are found on the dead bodies of enemies. The AI is absolutely brilliant in Oblivion. One example is if you are fighting two skeletons and one dies and you break the other ones weapon, the one with the broken weapon will go and pick up the dead ones weapon. Also there are tons of quests to play and many races and classes to be. you also get to pick a sign ypu were born under like Shadow which is what I picked and gives you 60 seconds of invisibility a day which comes in handy when stealing stuff. Also the quest system is great and will allow you to easily look at what to do in the quest. There are also makers on the map that tell you exactly where to go.
Sound: The sound in this game is great. The one bad part is that you'll often be talking to someone and their voice will completely change halfway through the conversation. For instance, if you talk to a beggar they will have an Irish accent voice and then when you give them a coin they will suddenly have a voice like the guards which is an American voice. Other than that it is great.
Value: This will supply you with endless hours of fun and thousands of things to do and explore the Elder Scrolls games are known for thir excellent replay value and this game lives up to the reputation.
