Simply a Mess
This is what happens when profit focused management stifles creative developers. The Force Unleashed has moments of fun but is so weighed down with a feeling of rushed, poor, uninspired design and polish that you will probably start crying (at least on the inside).
The 'Meh, not too bad':
Playing as Vader for a few minutes was pretty cool.
The Terrible:
Sparse check points are unforgivable in a game aimed to please a broad mass-market.
This feels like a linear and unfinished beta of InFamous. Want to feel like a real superhero? Play that instead.
Some of the worst controls I've ever used in a "big studio" game.
The jumping mechanics are so crappy that forcing us to platform with them is criminal.
Corners appear to have been cut everywhere possible, for example notice in the cut-scenes that the motion capture for everyones walk is the same.
More reliance on QTE than Shenmue.
