Star Wars all the way, especially on Wii. The cheats for it are wicked but I advise you to complete it first and comeplete it with cheats after, The Viking is a great game but Star Wars: Wars The Force Unleased is heartbreakingly short so I've comepleted it more then 20 times. You never get bored of it.
Both of the games are great but Star Wars is the one for me. Good luck with your decision.
