Picked up Force Unleashed: The Ultimate Sith Edition, and Force Unleashed II yesterday from Steam's $4.99 sale.
Sale is up for another 45 minutes if there's anyone else out there who hasn't yet picked 'em up but wants to.
Despite the fact that its design is hugely console-centric and I was playing w/keyboard & mouse, I pretty much couldn't put the first one down until I'd played all the way through to the end. Even on easy mode, that gave me 11 hours of playtime by which I feel well rewarded for my investment. Looking forward to the second one, but I think I'm going to rest for a day or two between
