The origin was a Japanese company till some random dude translated into the international language we know as English. Of course, that was RPG Maker 2000.

RPG Maker XP isn’t a good idea. Not to sound rude, but hardly anyone really pays attention to RPG Maker games anymore. They’re all practically the same and there’s no innovation coming from there.
