Heh, I can't stand Log Horizon either but for completely different reasons. I thought the first handful of episodes were generally alright but then the story started getting majorly masturbatory and wasn't very interesting. It culminated in an episode in season 2 which was a 20 minute long speech about how they were gamers and rah rah rah don't give up. Holy shit man. After that episode both my fiance and I were thoroughly done with Log Horizon.
The art also did take a nose dive after the first few episodes. I figured they had dialed in exactly how much viewership and revenue the show would generate and adjusted their budget accordingly.
If you're looking for a gamified anime I'd recommend Is It Wrong to Pick Up a Girl in a Dungeon. It's had a more interesting plot than Log Horizon or Sword Art Online, both of which took dips in the middle of their first seasons. My only problem with it is it can be a bit fan servicey in a boobtacular way.
