NP the main difference between the two is SAO is more about escaping from the VR world there trapped in, and long horizon is more about surviving in it as they have no way to escape. This will be a bit of both like SAO there will be a way to escape but unlike SAO there will not be someone to tell us how we will have to figure it out. Until then we will have to adapt to are new world and are new body's with world be pretty difficult for anyone who made their avatar a diferant size or gender to their IRL ones lol.
