I want to thank First_Endless for suggesting I should make a template.
MC:
A random guy wakes up on the release day of SAO, he knows about the plot and can't log out. He has past life memories and doesn't know what happened, but he decides to play the game. His personality is up to you.
Plot:
He accepts the reality that he will need to fight and beat the game and will found a guild after the 10th boss or maybe later. Every now and then he will have dreams or visions of the life of this person he reincarnated as. This body's life is tragic and troubled, but he has loved ones he needs to return to and mistakes that need to be righted, especially with the body's family.
The original body said some bad things to his family before the game incident. The MC who never had a family in his past life wants to try to have one in this life and wants to reconcile with his new family. There's no ROB.
Ending:
There isn't much to invent, the MC knows who the GM is, but he needs to be strong enough and also have strong allies.
He can beat the game with Kirito's help, I don't mind that, then he'll wake up in the real world. I would also like a timeskip in the last chapter showing how the MC is doing.
Extra:
The game will be a little more realistic, there won't be gore or anything like that, but it definitely won't have the shounen feeling from the original anime.
I don't want the MC to follow Kirito or stick to the original story that was rushed. Leave Kirito doing whatever he wants and make our MC follow his own journey, you have a whole world to explore and a multitude of inspirations from games and manga. I can give examples of skills and cool magic if you need.
I want the fanfic to end in SAO, if it goes beyond that the story will be horrible.
