There were 319 entries from 19 people. Here's how I've proceeded so far:

2 entries were removed for having non-alphabetical/punctuational characters.

60 further entries were removed for being too difficult to pronounce or for having overly unwieldy spelling.

65 further entries were removed for being obvious joke names, being too goofy-sounding, being existing proper nouns or slight variations thereof, having other possible ill connotations, or having multiple words, hyphens, or apostrophes (many of these were very good otherwise).

91 further entries were removed because...well, I didn't think they sounded like good names for a world (though many could be used for names of other places, people, or creatures). I just went through the list once at this step, so further removals could occur for the same reason later. Oh, and a few names were remarkably similar to names I already have in the game, so out those went too.
