James Klim, also known as Greviousrocks, JamesKlimProductions, or JKPRising, and formally known as Metaridleyfan1, is a YouTube gamer who used to do walkthorughs of games, most commonly Metroid Prime and Halo games, but nowadays does mostly informational videos, rants, and discussions on games, such as the possibility of a Dead Space 4, a Halo 6, or information on the upcoming Metroid Prime 4. His first channel was called Metaridleyfan1, which he did Walkthroughs on, before deleting it due to disatisfaction with its content and creating greviousrocks. He created JamesKlimProduction in 2010 to create better walkthroughs and discussions on games. He then created the channel called Rising Potential, which is now called JKPRising, to create rants, discussions, informational videos, and other such opinion pieces on games.
This is a combination of the featured channels on all three of his channels still on YouTube. There are 9 featured on Greviousrocks, 10 featured on JamesKlimProduction, and 7 featured on JKPRising, and some of them, but not all of them, overlap with the channels.
