I've signed up for the beta. I really want to like it, but I doubt I will.
I would absolutely LOVE multiplayer Skyrim, as in 2-4 player co-op, but when you have hundreds of people all running around being the dragonborn, and the village you just saved is still being attacked so ArthasLichKingDK123 can save it as well...It's just not the same.
Every time a new MMO comes along, I'm really excited, hoping for something that can hook me like WoW originally did, but it seems once you've played one MMO, you've played them all.
Get Boot Camp and Skyrim, it's worth it.
