I suppose alot of social commentary slips into my games. I realized that I almost always cast the church as being secretly evil in the campaign worlds I create. And I'm much more likely to have rich bad guys that mistreat poor people than a downtrodden indvidual who desperately resorts to evil. Sometimes I do it on purpose, but I think its usually my own world view coloring the situation.
On 911 and DnD: After that happened, the first thought I had was, "Wow, I wish my characters could pull off something like that." I immediatly felt ashamed, and repeated to myself that obviously I was completely against the attack, and regretted that people had died, etc... But the way that adventurers in operate is alot like terrorists. PC's want to destroy the evil empire by killing its evil wizard ruler, or smashing the magical crystal that gives its soldiers their power or something. We want to blow up the Death Star, because its more exciting than starting a reasoned discourse, using the democratic process, or staging a boycott against the blacksmith. We conduct covert acts of destruction, because there's no way that our four PC's can stand up to the goblin king's large army of conventional forces. Trying to fight them openly on the field of battle is something only a lawful stupid paladin would do! But, its ok because we're the good guys.
