I think we all are aware this game is about grinding and getting levels. The reason people keep playing, I think, it's that when you are new on the game, you see higher levels, and powerful armor and you say "I'm gonna get that someday". Turns out it wasn't as easy as one thought when one starts the game, but we do it anyway, because we want to reach our goals, locked forever on the game to earn sick amounts of money/XP. If someone told us at the start that we were going to be countless hours doing repetitive actions just to get a piece of armor, then most of us wouldn't been playing now.
