I bought the PC version and to be honest with you it plays flawlessly. It's a fun game, I've certainly played better but for $30.00 I'm enjoying it very much. The only thing that sucks about it is the huge 25gig install... that's INSANE!! That's probably why you are not seeing it on digital download services. I don't understand how the PC version is 25gigs but they fit the whole XB360 game on a 8 gig DVD? I didn't notice any graphical improvements from the console version but it's a nice looking title either way. I'm grateful it came to my platform of choice and I plan on grabbing another copy for my son. By the way, the Star Destroyer "pull down" is the worst part of the game IMHO.
