What do the sword gods SAO, SAOP, ALO and GGO mean?

As an iron fan of Excalibur, I have too much say in this issue. These Sao and SAOP mentioned above refer to the names of Jian Zhang, and these English letters are actually abbreviations of some English words.

SAOSAO is an acronym for word (Sword Art Online). Translated into Chinese is the realm of sword, so Sao refers to the realm of sword. The content of the first season of Excalibur.

SAOPSAOP is an acronym for word (Sword Art Online Progressive). Translated into Chinese, it is an attack in the sword world, so SAOP refers to an attack in the sword world. "SAOP" was written by Kawahara after the broadcast of "SAO" in order to meet everyone's needs. It also tells the story of Tongren and Asina in Ain Grant.

ALOALO is the acronym for (ALfheimOnline). Translated into Chinese for the leprechaun kingdom, so ALO refers to the leprechaun kingdom. It is called fairy kingdom because there are many elves of different races in this game, and they can fly. The game that the Lord will play after Tong Ren Li Sao.

GGOGGO is an acronym for the word "Gun Gale Online". This is a gunfight game. It was in this chapter that Tong people met Snyder.

UWUW is an acronym for the word "Under World", which is translated into Chinese as the underground world, so UW refers to the underground world.

URUR is (unified ring), the acronym of this word, translated into Chinese, is a joint ring, so UR refers to a joint ring. UR is the world closest to our real world. Once a player dies in UR, his account will be permanently cancelled!

The above is the information that these letters refer to in Sword of God. I believe you should know after reading it.
