CRASH is the name of a VRMMORPG created by the MC that combines all of the different VRMMORPGs from Anime which all exist in that world at the request of the Reincarnator.
CRASH allows for the power from all of the different Games to be stored on a single save and be combined into a person's Unity, (name of players in the main Universe) the players, whilst playing the separate games can do all of the standard stuff and afterwards all of the power is compiled together, all abilities, bonuses etc. Into the main body.
Currently I'm thinking of having "Yiggdrasil", "SAO" and a few others in the world, but to achieve this idea properly I'll need the help of all you readers, and possibly other authors, due to my notorious unreliability in the creation of these fanfics. I'd like a lot of people (if possible) to submit their ideas for how this might work in the chapter comments so that I can try and create something that has a little bit of everyone's tastes.
I'm thinking of long chapters with the MC dipping into the different Games for about 10-15 chapters and then switching, before eventually going back to the more popular games, as well as having moments in the mixed universe where all of the cool abilities can be showcased in things such as tournaments and the like.
