One thing that I think could really help would be subdivisions for states/provinces/regions. Some parts of countries are far too easy to hit, simply because the country is tiny. Others are a complete stab in the dark unless you already know the name of the place. Canada, United States, China, Australia, India, and Russia would especially benefit from this.
No mute button made it impractical to play this game in my setting. Not going to rate it, but looks like it has promise. Just a simple setting that really should be there.
