This is a survival server with an economy, so there are a lot of ways to make money while you play. You can work your way up by grinding, trading, or just finding your own hustle, depending on how you like to play.
You can beat the game in multiple ways too. Go for the Ender Dragon, or focus on becoming the richest person on the server instead. It keeps things open and gives you a couple of different goals to aim for while you survive.
PvP is part of the mix as well, and with crossplay support plus MCMMO in the server, there is plenty to do whether you want to fight, progress, or just build up your stats over time.
