Walled cities aren't that big of a deal to me, the removal of attributes seems logical at this point, and the depth of exploration in TES games has never been matched. Skyrim will be a great game.
You know you're going to be crucified for being an "over-zealous fan-boy", and accused of being a "console [insert derogatory soundbite here]", and blamed for all that is wrong with Tamriel, right? But I tend to agree. I haven't seen or heard anything that's going to break the game. Walled cities? So what. No attributes? Good news. No spears? Yawn. Can't ride dragons? Thank God... that's a dumb idea anyway. I think exploration looks great just based on the varied geography alone. Whether it makes me a mindless fan-boy or not, the game looks like many hours of fun. Honestly, I'm kind of tired of the "I've been playing since Daggerfall and they're dumbing it down" chest pounding and the "My hardware is far superior than your wimpy console" attitudes. I'm excited to play the game. Can't wait! (Or is that phrase trademarked now by that idiot Jets player?)
