I really want to like this game.
I love Tim Schafer games. Grim Fandango and Psychonauts, his more recent creations, were awesome. The art design, setting and story were enthralling and lovable. And the same goes for Brutal Legend. The metal world Schafer has brought to life is fantastic. The character designs are brilliantly imaginative - This is the kind of game I'd love to work on.
Then it comes to the gameplay... The driving and basic combat is fine. It's the RTS moments. I've found them boring and repetitive and this makes it difficult to continue playing. I'd about half way through I'd say and I intend to finish it - Just for the story and to unlock the concept art.
