I just finished Bioshock a couple of days ago. An interesting take with plenty of twists. Toward the end I was just trying to finish the game, and I really stopped caring about the scenery and effects, etc. Maybe because I was playing it on a 25" TV instead of my 84" screen (Home theatre still under "re-construction")
I played through as a good guy rescuing all of the Little Sisters, is it worth playing through the game as a bad guy? Is the ending all that different?
I guess if I have to ask the question, I've just answered it myself.
