Most playerworlds have that since one word names are more likely to be the names of countries or planets then two word names are (At least that's the case with most countries in the english language with a few exceptions, those few exceptions usually being that the name of the country could be said to be a description of the country), and it's ussually easier to think up one non-existant word as a name then combining two existing ones in an original way.
