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.
