nostalgia is blinding you
Yeah, if I was to answer this, I had more fun on servers a few years ago.
But, back then I was younger, had fewer responsibilities, could play for longer, and had friends who were also actively playing the game who I could join.
Today I'm older, have other responsibilities that I have to attend to, can't play for as long, and my friends don't play the game so much (mainly for the same reasons as me).
Also to be fair, the most fun I ever had in Blockland was playing on MY server or on my best friends server, where we did what WE wanted to do and people joined us.
Playing on other people's servers was fun for the most part, but we always enjoyed our own servers more. That would be the same today.
