The "Force Unleashed" concept doesn't bother me. As long as it's at least as fun as Dark Forces, Dark Forces II: Jedi Knight, Jedi Knight II: Jedio Outcast, and Jedi Knight: Jedi Academy, I'll be happy.
The pre-vis itself (also available on youtube) is interesting- look at the Stormtroopers. They're like Clonetrooper Phase II (RotS style) suits mixed with the classic Stormtrooper helmet. I wonder if this is just hasty rendering or indicative of a post-RotS, pre-ANH game setting- which would be pretty fun.
Of course, the last level would have a door open and Darth Vader step in, and then he would kill you.
I like the way they think:
In terms of being "accurate" with the use of the Force, we're committed to creating powers that are logical and believable extensions of the Force as seen in the films, and provide tremendous gameplay opportunities. As a diehard Star Wars fan myself, I know that one of the big questions fans have when they see the video is "Why is that Jedi using Force lightning?" It's a legitimate question, but we think it'll make a lot more sense to everyone once they know a bit more about the story. I think we've got a story that will please everyone from the most hardcore to the most casual of Star Wars fans. But we're not talking about that just yet…
Many of us will be familiar with that concept, and annoyance at the whining that, for example, a Jedi can't crush someone's skull as easily as he can crush a metal column (Dooku, AotC), because ... just because.
