Why would they think a multi-billion dollar company like Nintendo would be cool with folks using their IP? The light bulb should have definitely go on when they forced Pokemon Uranium to cease and desist back in 2016. How are they going to live out there Pikachu inspired dreams now? Truthfully, I’m surprised people didn’t see this coming for years, when the creator(s) first came out with this system. Needless to say, folks aren’t happy about this. All of these will probably have to shutdown, if they haven’t already. A lot of good games were made using it (I’m leaving out the POKEMON as all the titles have it): Reborn, Insurgence, Sage, Obsidian and, most notably, Uranium.
It’s been recently announced on the RPG Maker web forum that NINTENDO has decided to put the kibosh on the Pokemon Essentials, a customized set of scripts used by fans to make their own fan games that started back in the days of RPG Maker XP (circa 2006).
