I voted "too soon to tell". I don't see how a game on this subject must automatically be distasteful and offensive. Not talking about a problem doesn't make it go away, and that's true even for the victims of tragedies. I think a roleplaying game would have an immense potential for understanding and learning as much as possible from a tragic situation. To understand that not all arabs are terrorists. To learn that even terrorists aren't child-eating demons. To understand the politics of the area. To see beyond the easy "kill them all". To witness what deep propaganda can do to people. To help understanding that even the most evil murderer in the world has human rights, and to see what happens in a nation where this principle is violated. I could go on for pages... If it can be fun too, so much better.
