Apparently, the Wii version has had a lot more thought put into it than just a straight "must-shoe-horn-motion-control-scheme-in" mentality, to the point of having a virtually separate development team, or so Gamespot's coverage would have you believe. Not always the most reliable, I'll grant you, but when they
post interviews claiming as much, you gotta at least take it into some kind of consideration!
...the Wii version will have some levels that aren't in the Xbox 360 or PS3 versions. In the Wii version, we saw a Jedi temple level, but more importantly, LucasArts demonstrated how the Wii Remote is used for lightsaber attacks while the Nunchuk is used for Force powers.
Good to see a developer actually using the technology's strengths for once, and using it as an excuse for lazy, half-arsed ports!
Just spare a thought for us poor PC gamers... I chucked all my money at my rig last year, so no Force Unleashed or Soul Calibur IV for me just yet... Oh, well, maybe just in time for the both of them to go budget! :D
