A month ago, I completed the Main Storyline of Elder Scrolls 4, along with becoming the Arch Mage, Grand Champion of the Arena and Master of the Fighters Guild.

I recently decided to complete the Dark Brotherhood and Thieves Guild quests to get all of the 50 achievements of Oblivion. I just have to say that The Dark Brotherhood is so cool, and I love becoming a vampire, it really adds to the atmosphere and ambiance of the whole silent killer thing. The funny thing is, no matter how depraved the Dark Brotherhood is, they have rules and some semblance of honor. Still, it's kind of fun to be the bad guy after saving Cyrodiil. In fact I got caught murdering someone, but the Imperial Legion guy who saw me do it just said "You're in a lot of trouble, but since we are friends, I will take care of this". Basically, I can actually murder a lot of people and because of my fame they forgive me.

Oblivion is a really great game, I just wish there were a lot more mods available for the 360 version (which is worth getting, the PC version costs as much as an Xbox 360 if you have to buy a new video card... or new computer entirely, lord forbid).
