Give a summary of what's there and I'll point out any big missing things if any. Cba to read all that. :/
Can't be bothered?
It first explains that it's about heroes coming together to save Existence, and that all the plots are created by the players. It explains that we don't follow a strict path, because it's all made by everyone. It explains that we have no GM, but instead that we make decisions together and that two of us that joined later on now are a part of that. It explains our posting style and why we use it: to learn to understand and imply in the shortest manner.
It explains the "Myriad Reality is real" thing, how IC is more important than OOC, and briefly mentions the need for adaptation (elaborated upon later). It explains that it's not easy to start up; it explains how it requires dedication to adapt. It details the stories of two potential players who wanted MR to adapt to them, but ultimately failed. It explains that we're not desperate and we want the kind of people who know how to think and adapt--or wish to learn.
It explains that Myriad Reality falls into none of the categories on this site (and subtly mocks Advanced). Then it explains how the characters are OP by other RPs' standards. This is the main part that might need help--the part starting after "Okay, so you're probably wondering..."
