I thought it was way too hard in the beginning ( vs Dooku) but after that it was too easy... It's too bad that you can't play as another Jedi in singleplayer , or even as Sidious or Yoda in the versus mode... The multiplayer co-op mode was like a little bonus... It was waaaaaaay too short....
I hope that the people at lucasarts will decide to create a game like ROTS , but one that covers all the movies, and in which you can play as every jedi ever been seen in the movies and features an expanded multiplayer (co-op mode)....
