No doubt that is a good step to make more understanding of the Arab culture. - somebody with a hijab with a gun :D
If I would like to go to Arabia, I should know about Arabic culture. If Arabic people are coming to EU (e.g.) they should learn how we live here and respect the rules... I'm not sure, how it would go in Arabic/ muslim countries spreading European culture.
People are different, with different culture and beliefs.. so it be, but game with somebody in hijab as a tool to find out more about Arabic culture is ridiculous :)
As a game, fair enough.. but other reasons would be silly
