I'm uploading a US townnames NewGRF that contains nearly 1000 town/city/burrough/"CDP" names. To make it seem "American" I tried to restrict it to places that exist in 4 separate States. I like more generic town names than major ones - there's nothing worse than having New York City on the west of your map and Los Angeles at the north - places like "Springfield" are common enough that they could appear anywhere on the map.
I used a method similar to that documented here http://en.wikipedia.org/wiki/Talk:List_ ... lace_names
except using a different set of names.
Clinton was the most common place name in my list, followed by Franklin, Fairview, Greenville and Salem. The proportions are reasonably well preserved in the NewGRF.
It should appear up on Bananas once everything is processed.
