Your article on being bad in games was interesting. However, sadly 'being bad' is something else that's hampered more often than not by bad writing. Of course, it's great fun (in a rather juvenile way) to play Ming the Merciless or Darth Numbrod - to play someone who knows they're evil, who embraces their moral vileness and who enjoys nothing more than crushing star systems under their heel and laughing maniacally.
But it's not very complex. In many ways, it's just as simplistic as playing the farmboy-become-saviour, just with cooler clothes. How many people really see themselves as evil? Even the poster boys for evil throughout history saw themselves as the good guys. What would be miles more interesting than playing Mr Evil Cackle would be playing characters that think they're the good guys, even if the player knows that their actions are questionable. Characters that believe they're committing murder for a greater good other than getting some cool loot for their Evil HQ. In so many games, good and evil have the depth of a Halloween mask, and that's disappointing.
As a sidenote: What I enjoyed about TIE Fighter (apart from the coolness of piloting an Imperial craft and the obvious gameplay improvements over X-Wing) was that the Empire was presented as a force that saw itself as striving for a noble goal: bringing order to the galaxy. When I jumped into the cockpit of my trusty TIE Interceptor, I was doing so because the rebels were terrorists. Not because I was one evil mother. And that's interesting storytelling, as far as I'm concerned.
