Frontline Combat is a modded team PvP server that feels like squad battles and battlefield style fights.
It runs regular events every week and the staff keeps trying to make each one better. They also have their own custom mods and extra content so it is not just basic PvP.
This server is Java only and it is mainly about team play and getting into big combat situations with other players.
Billionaire City is a server that tries to mix normal Minecraft with more long term goals. It runs on 1.21.X and has two main game modes that feel pretty different from each other.
The first mode is like boosted survival. You still start small but the world has extra progression systems and challenges. It pushes you to explore a lot and slowly grow stronger. You can farm build fight and work with other players to make big bases and empires.
The second mode is more like a tycoon game. It is all about earning more and more and building up an economy. You focus on setting up systems and improving how your resources move so you can keep scaling up and reach higher tiers over time.
Both modes are made to feel polished but not too confusing. The server wants players to experiment be creative and play together. There are plans for regular updates and events so things do not get boring fast.
