Unfortunately, some companies have been remiss in their efforts to port games to the Wii. Because of the number of abysmal ports that have populated the Wii, gamers have, for the most part, conceded any hope of a great port on the system. According to Mark Combs, Star Wars: The Force Unleashed for the Wii is a port of the PS2 version. Hopefully Star Wars on the Wii will restore some faith that ports on the system can be developed successfully.
"Well, the lead development has been done in Brisbane on the PS2, and that is the first point of call with all workings between Lucas Arts and Krome. So what we're doing here is taking the PS2 development, putting it on the Wii, and making all the Wii specific stuff here. So, lead point is PS2 in Brisbane, to make that clear." - Mark Combs (Producer of Star Wars: The Force Unleashed)
