Runescape. The first one.
I was into mining and smithing, hoping to make really good armor before getting into the game proper. But it scope creeped you like a B. It was always just a little more before you could get the next set... so in practice, I ended up just mining until I got bored and then quitting the game.
Oddly enough, I learned a life lesson from that. I had just unlocked the ability to mine iron, and sometimes it was crowded and the players with higher mining levels would get everything, in a quite unfair positive feedback loop. So, naive as I was, I protested in the chat to leave this one over here for me. I considered that more than reasonable. There were several of the ores and they would refill every thirty seconds or so, so it wouldn't really slow them down at all.
One of the players did at least take the time to respond: get a better pick, or go back to tin.
It might sound rude, and that was probably even the intent. But instead of focusing on that, I realized he was right. The world won't bend for you, even if you think it's a reasonable request.
I went back to tin. I was hell-bent on smithing all my own supplies, lol.
