Game owns and I was glad to see it beat the pants off MW3 this weekend. At one point nearly everyone on my friends list was playing it on Friday, I haven't seen that happen since TF2.
I went with a bow/sneak type character but I'm having trouble in CQB, the daggers suck for anything but sneak attacks. I really like the perk system and how they divvied up attributes this time, it allows for customization without getting too punishing for "wrong" choices.
Exploring is just fantastic, there is shit everywhere. I already ran into something like 4 dragons just exploring west of Whiterun. I found countless caves and ruins too, there is just a ton of content in the game and some of it is downright creepy. NPC interactions are a lot more satisfying this time around and the animations aren't oblivion jank.
