EternaSMP is a survival server built for grinders. If you like working your way up, there are 29 unique rank tiers to climb through with in-game money, and 6 different jobs to help you earn it. It is very much set up around progression, money making, and always having something new to work toward.
There are also 60+ custom enchantments that add new abilities to your gear, so upgrading your tools and armor actually matters. On top of that, you can compete on the leaderboard, throw your money into coinflip, and use player shops to buy and sell with others.
If you want a survival economy server with lots of progression and a reason to keep grinding, EternaSMP is the kind of place to settle into. Cosmetics are also part of the mix, giving you a few extra things to unlock along the way.
