Jesus H Christ this game is so ****ing good
When I tried oblivion I couldn't really get in to it, but this one has me so addicted. Really nice graphics, breathtaking scenery, huge world, amazing immersion. I've already clocked 30 hours on it and I've barely scratched the surface, so much cool stuff you can do. Best thing is it's such an open world with so many possibilities that you could play the game through 3 times and have different experiences each time.
Currently rocking a high elf mage, I've just completed the mage-college quest line, am now the college arch-mage. Got some sweet gear out of it
And yeah, get it for PC if you can, DA is spot on.
