EDIT: Looks like that is when the git history started, but from the responses here it sounds like this started more towards mid-2000s

Anecdotally, I've used it to play a few RPG Maker 2003 titles to completion on a Raspberry Pi.
It's funny that the Official owners also uses this fanmade app on one of their products.
However, given that RPG Maker 2k/2k3 games often have compatibility issues running on modern Windows, it would make a certain sense if KADOKAWA used EasyRPG as a way of extending compatibility. Then too, I'm not really aware of their relationship to the games produced with their tools (even ones that could be considered historically significant, such as Yume Nikki), so I don't know how likely this outcome would be overall.
Searching the web, I found the old forge (same project name, same first developer name) at Google Code Archive. The oldest commit is dated 2006-01-16, so it's at least that old.
EDIT: I found an interview from 2008 with the project creator (https://comunidad.rpgmaker.es/d/8745-entrevista-a-delapipol-..., in Spanish) where he states that “it was around 2005 that we thought of making a free alternative to Enterbrain’s RPG Maker”.
Answering my own question - it appears from the top response here that the editor component is not yet ready
EDIT: I am not sure how many non-English or non-German games this contains.
