Sorry to say, but essentially ANY name that doesn't involve an aesthetically nightmarish jumble of letters and numbers at the end is gonna be taken.
You likely won't be able to get:
- Spirits and animistic nomeclature, no matter how obscure
- Any variation on your own name
- ANY animals. AT ALL without adding the obligatory "777777777" to the end.
- Anything ironic (ex: placeholder, insertnamehere, namenotfound)
- Gods, demons, anything like that.
- Emotions.
- Famous people/places/events.
There was once a time, so very long ago, when 52kbps was epic broadband, where you could take any name you wanted... This was the original internet... *nostalgic sigh*
People have been saying that the world was too full of people since the Renaissance, as anyone who lives in or remotely NEAR a major city can tell you is completely true. It's becoming increasingly evident online as well.
