Nah, not yet. It's in my top 10 games I'm picking up next, just waiting on a steam sale for it, which will happen pretty much the day after I buy it fullprice. I was wayyy to heavy into Rift when it came out to even blink at other games existences, but a few of my guildies seemed to like it.
But, like Dead Island before it and Borderlands before that, they played for like a week then never booted it up again.
Skyrim is currently owning my gaming life. I think my main dude has like 70 hours played on him already and I'm not even half way done with the map. I've pretty much not gone west at all from the point where you're supposed to go to High Hrothgar, but I'm about 90% sure I've unlocked everything else (caves, ponds, towers, etc etc) on the entire right half of the map.
Don't start Skyrim till you have at least a weekend to give to it, or you'll be hatin yourself.
