In the past few days I didn't get up from my PC, because I was playing Elder Scrolls IV Oblivion. In the game I get few mods one of them was about Viconia De Vir, companion mod and the Underdark Saga, well I will say one thing: for the moment I am 100% addicted to Oblivion, because it's firs person RPG and it's well WoW offline with thousands of quests, items and creatures if you get bored, just go and download few mods or DLCs and you will never be bored again.
Here's few sitesthis one is one of the greatest. Check it out.
