I found a server called CrownMC RPG and it feels like a big open world survival MMO. You pick your own path and just start building your character with a bunch of skills you can level up.
You can farm for a chill life or focus on crafting and fishing. If you like money stuff there is an economy with shops and an Auction House where players run the market.
There are custom bosses and dungeons too and you can go raid them for special gear and crate keys. Health scales up as you gain experience so you can get way tougher over time.
The wild twist is the monarchy system. The crown is a real thing and if you find and slay the current King you instantly become the new King. You take their claims and can zone their kingdom. It is optional but it makes the server feel like there is always a power struggle happening.
You can also party up with friends and level together. It is basically an RPG SMP with roleplay and PVP if you want to chase the crown.
