And those three posts couldn't have been put into one... why?
Anyway, from my experience (playing 2-player with my friend, who owns and likes this series), it just seemed to be brainless hack-and-slash, no matter who you picked. The enemies, for the most part, all seemed to have been trained in the art of Standing Around And Attacking One At A Time Fu.
And the environments seemed awfully flat, in my opinion.
And once again; Why do you have Gollum for your user pic?
