Should governments have the right to ban certain games? Why or why not?
Although Ithink those games bring disvantages, I think the government should not ban certain games.

It is because the people should have human right to play/develop the game, and I think the government have no permission to stop or avoid it. Also, it is so difficult to prove that playing video games is the main reason of causing violent crime (e.g. murdering), maybe it happens because of other reasons.

However, I think the government should set some limitations of playing certain games because it really affect the growth of children. For example, the government can set up the age limitation, to avoid the child play or be touch with those video games. To avoid the violate crime, the government also can have more promotion and education on public.
