I don't know if you guys noticed this or not, but from the picture of the Elder Tale during beta, there were this numbers on the top left:
If you guys look even closer, you'll notice that the first 8 numbers are date, in a sense.
Which means that the game was out during October 22nd, 1998. And it was said that the game was already said to be 20 years old. This means that the events that took place in Log Horizon happened sometime in 2018.
What do you guys think about this? If this game existed in our world & the events happened, what would you do?
Don't think what would you do with your head cool. Think as if you're in it right now.
