It has brought back a lot of the grittiness and atmosphere that was in Morrowind (which had been left behind in Oblivion), and it has improved upon the beauty that was in Oblivion, which had till now been my favorite game.
I've been playing for almost a week straight now, and yes I've had a few CTD's, but that's nothing new for most games. For the most part, it runs fine, and I have a mid-to-low end POS PC.
I am dying for the CK, but for once there really isn't a lot that needs to be changed. I just want to add more of the same.
So thanks Bethesda, Todd, and team for a work of art.
