@Kiriha Well if you take "things not taking place on earth are isekai", then that's a whole other problems. Series like Index would be isekai. So would almost every Space Opera. "Legend of the Galactic Heroes is my favorite isekai" or "Cowboy Bebop is my favorite isekai" makes no sense. Of course there are exceptions, "Flash Gordon is my favorite isekai" does make sense, but most people wouldn't think of it that way. Then you would come run into series that muddy the waters lIke Planet of the Apes (to avoid spoiling manga, I'll use a movie as the example).
@Kampfarsch That part of the screen isn't typeset, it's from the raw. The only text on the screen that I changed was the "ARK EARTH ONLINE" bit above it.
@amamiya426 Considering the current game naming scheme, I'm surprised it wasn't something like "1337_Wiz". It already show plenty of creativity in naming, most likely after the name "Gandalf Dumbledore" was taken by someone who camped by the register page when the server just opened.
