A mix between Lyn's story and fe6's tutorial would be nice. Fe6's tutorial is small, yet teaches almost everything you need to know about the game at the most basic level. things such as: Visiting villages, talking to units (not enemies though), and seizing the throne. The reason this works is because it isn't a 10 chapter long mandatory on the first playthrough tutorial, but it only teaches the bare minimum. The reason Lyn's story works is because most things you do carry over into Eliwood's or Hector's story, and it teaches you almost everything, including rain, which only happens in 2 chapters in Eliwood's and Hector's stories. The problem with Lyn's story is that it's too long, while fe6's tutorial teaches too little for a new player who has never played a game like Fire Emblem or know anything about Fire Emblem, while Lyn's story can turn of fans of the franchise because of how long it is. A mix between them would most likely be a short, 4-6 chapter tutorial that teaches new players how to play the game, but is interesting, engaging, or fun enough to keep some of the more impatient fans (or people in general) playing.
