Certainly there is a market for violent gaming, but I wonder if there is an ethical line that companies chose not to cross. For example, there are presently several games on the market that allow players to rape women. There are also games that allow players to dress as terrorists and kill American soldiers and civilians. Although these aren't illegal, they might dance on the edge of acceptable.
We also have to deal with issues of legal content. For example, instructions to build weapons can be illegal (depending on the type of weapon). Content can drive business, but it can also be an expense if it is illegal or social condemned.
And then there is the issue of country specific content. What is acceptable in one country might not be in another.
So, what are some guiding principles we can suggest to our client about how to evaluate content for their games (and other media)?
