some people like it a lot, personally i didn't like it that much
If you want to watch something else like SAO, i suggest Log Horizon, imo one of the best anime in the past few years. Players suddenly realize they are inside the MMO they were playing when a new expansion was released. They have no idea why they are there and how to get out, so they start to make a living in their new world, but a lot of social issues arise.
The first seasons revolves mostly around building a society in a world with virtually no laws (other than not fighting in cities), a world where killed people are automatically revived, a world where you have people with godlike power (max level characters) and more or less normal people (newbies). And then there are the NPCs, which do NOT revive when killed, how do players deal with them and their problems, although they don't affect the players who already have enough to deal with.
The second season is currently airing and isn't as good as the first imo, but still very good. It's more about fighting, how to do a new raid and fight bosses in this new world, how to keep going if you are killed over and over for days. And what happens when the only law the world had suddenly isn't true anymore. It's also a lot about personal growth of several characters. The next arc in the second seasons seems to be about how to deal with players from other cities, which have built a completely different society.
