In fact, after finishing SAO, the first SAO is very empty and doesn't have as much stuff as today's SAO.
The only thing I wanted from the game is to have more freedom, where you can sleep as much as you want, explore places and do a mission alone, you know? In this current one you have more freedom than the first.
I like to enjoy the world and when it's RPG Maker, I love exploring places, enjoying the dialogues, views and so on.
It's not about being boring, as I'm a lover of history and exploration, it's important to have both in the game, in addition to having a lively game and Fujino has improved a lot and lacks a little freedom.
