I was wondering seen as the latest game took so long to be able to unlock character customization. I truly believe you are missing the biggest trick of all when it comes to the SAO games and its genre. I would love to see an open world MMO in the works where we can create our characters from the get go and experience the worlds and each season along the way, each season could be compacted into an expansion and span a set amount of time. the possibilities with turning SAO into a proper MMO open world game would be amazing. take tips from the Pokemon Sword and Shield Games if you must for a world that feels open even if its not.
This is something that I feel would rival even the biggest games if done right. I truly believe the SAO games if done right would be a great platform going forward.
