Simply Mind blowing.
This is an Amazing Singleplayer Roleplay game and unique in its own way.
Sound : The sound is excellent blends very well in with the Environment and fits good, not much else to say really.
Graphic : Using a great Graphic Engine for this game makes it looks so realistic and really Amazing, Ofcourse you need a descent computer, but if you do, and are able to turn the Settings on high you will see the true power and Greatness of the Graphics.
AI : The AI is pretty good, i havent seen any major imperfections yet im sure there are a few glitches but up to now its all been running smooth.
Gameplay : It feels very realistic and you can easily get lost in it in a away, the great graphics, sound and all that make it very fun to play. There is alot of content, for example there are hundreds of quests you can do, all big and small, most of them are very unique and fun so they never get boring. Great leveling system so you can choose attributes relevant for your class. Tons of weapons, armor, rings etc you can find through out the game, many with good bonus attributes. You can also learn Tons of spells, from summoning Creatures to Telepathy and other destructive or useful ones. Around 200 hours gameplay involved roughly, and yet so much to discover.
Conclusion : Definitely the best RP game i've played up to date, with a good storyline, strongly suggest this game for anyone.
