The game should stay and be available.
1. People always brag about protecting the freedom of speech even if that offends others. This seems to be ok only when those offended are not from the west or don't agree with the power-that-be. If freedom of speech is such an universal value, then this should be accepted.
2. The US as a state always preys on other people's misfortune, they've went to great lengths to even destroy two countries, I don't see why people are complaining when someone profits from the misfortune of the americans. Grow up and live with this.
