The thing I liked about the Xbox version were some of the achievements you could get. I've become addicted to trying to get a bunch of the achievements in the Xbox 360 games now. I finally almost got them all in Halo, and they all of a sudden decide to add a bunch more you can get. I almost screamed. I also love trying to find all the "Kilroy was Here" graffitti in the Brothers in Arms: Hell's Highway game. Some of those are hard to find. Anyway, off on a tangent.
Anyway, at the opening of the game, when you're playing as Vader, you can get the aptly named (if anyone's ever watched Chad Vader: Dayshift Manager) "Worst Dayshift manager ever" achievement if you take out enough stormtroopers.
Have you guys seen any of the easter eggs in the game? When you're in the first level, in the Tie Fighter manufacturing plant, when you first go out into the open walkway where they have the TIE's flying around and shooting at you, go to the end of the first walkway on the right, jump up on all those boxes at the end of the walkway, and there is a Scorch helmet hidden on top of the area up there.
They also have an X-wing on Raxus Prime you can lift out of the muck, a nod to the Dagobah scene in Empire (it just sinks again after you let go----do or do not...there is no try), as well as some C-3PO pieces on the ground when you first land on the planet, in pieces like he was in Empire. When you escape from the Imperical, they announce that "subject 1138" has escaped. On Imperial Kashyyk, check out the hut with all the trophies. It has Jar Jar in carbonite (justice is served), and some other famous Star Wars creatures heads mounted on the wall, like Salacious Crumb, those mosnters from the Ewok Adventure, a Krayt Dragon, a Dionoga, and some others. On Imperial Raxus Prime, you can also see a Millenium Falcon style freighter in the wreckage, as well as some of the prequel style star destroyers. Very nice touch.
So, which level do you like the least? I know trying to kill off that 2nd Jedi was hard as crap for me. What sicko designs these things? First you almost kill him, then comes the trash monster droid, you have to almost kill him again, then another monster droid, then you finally can kill him for real. I almost put my controller through the TV on that one. Shaak Ti was surprisingly pretty easy. Haven't gotten to the Star Destroyer yet, but they said the thing to do is hide behind the pylons so you don't get hit from TIE Fighter fire, then catch one when it gets close enough, then hurl it into another TIE fighter until they're gone, so you can force grip the star destroyer. Rinse, repeat, until it comes crashing down.
