It truly is, I give it a yearly rewatch, sometimes even twice a year. It never gets old. The time-traveling episode in the second season always makes me tear up as well.
Sadly they probably won't be making a fourth season and if they do I'm guessing they're going to let it be made by a studio that won't do it as good as Doga Kobo.
What's interesting is that the second season of New Game (also done by Doga Kobo) shows a poster twice which was literally just a shot from Yuru Yuri's ED.
