Well I don't mean to get in the habit of posting about every single game I play, but this one was unusually good. All the reviews I've read also typically give it the highest ratings. The gameplay is a third-person perspective of your characters, up to 3 at once, with an intuitive interface for interacting with things and engaging in combat, all of course in a universe consistent with Lucas' vision of Star Wars.
The whole time you play you're given opportunities to play for the light or dark side.
This round I chose the light side, but I assure you in conversing with a number of idiots
in the game I was always tempted to choose the responses towards the bottom with scathing
comebacks or bullying tactics. I've considered playing again and giving in to the dark
side, as I understand at some point in the game (towards the end) your choices actually
change the outcome of the game. It would be fun to try, but it is a pretty long game. I
did try it for about 30 minutes, and while I found the dark side responses fairly
satisfying, it didn't really change anything except to elicit astonished or chiding
remarks from your companions.
Give it a try. It's fun. Xbox now, out for PC soon.
