There's nothing racist about a game. Sure, it takes cultural/historical differences and put it to the front but that's about it. What are we gonna say to games like Through the Desert which have arabs on camels, Santiago... we could go on for quite a while here. These are just games and they all need a theme, that's ALL there is to it.
Most things can be perceived as offensive if you squint and look sideways enough. What I find offensive are the people who feel the need to do this with the most innocuous of subjects. All this does is stir the silt in otherwise clean water.
