Another tone will be set in Pokemon World with the new version from the previous sequence. You'd imagine that Pokemon "Prism" is going to meet the same destiny as other recent Pokemon fan projects. Nintendo and Pokemon Co. will swoop in soon enough. That's a real disgrace because this project has been approximately 8 years in the making. It's due to release to the audience by December 2016.
Not long after fangame Pokemon Uranium launched, another fan project, Pokemon Prism, is rapidly coming to its release--and you can play it right now. probably.
As it was elaborated in a recently released trailer (below), it was never imagining that Pokemon Prism has been in the progress for nearly eight years the characteristics of the new story, is having more than 200 Pokemon, a new region to map and explore for new types, and emerging abilities to play as one of your Pokemon, among other things. It's intended in the style of a Game Boy Color-era Pokemon game but features 60 FPS gameplay. Fans are hoping for Andriod and IOS version for mobile.
Being a fan game that composes the use of the Pokemon IP, there will certainly be interests that lawyers for Nintendo and/or The Pokemon Company will take a motion to shut it down. Those behind the said Pokemon Uranium, also a fan project that was permitted to be for free, were bound to remove download links for the game after takedown notices were issued. The game is still accessible ready from certain places online, but the developers have since deserted the project, which was in creation for the past nine years.
The builders behind Prism don't seem to be anxious enough by that prospect, as releasing a preview and debut on Twitch are clearly moves intentionally to attract attention. It remains to be seen what transpires from here.
