Finished playing, kind of disappointed for the update, not much new scenes most of them are just new characters and maps.
I prefer more about the old map than the new one, the new one is just too much space for gameplay, sure it is bigger but not very useful for the freeroaming, kind of like the open world of EA's games, have lot of space but not much to play on the map.
The developer said part 2 will be more using the original SAO characters than to create a new NPC characters, it will be great if you are also a fans of the SAO.
