SuperScroobs MC is a survival server with a pretty chill setup: keep experience and keep inventory are on in the Overworld, Nether, and The End, so death is a lot less punishing outside of PvP. It keeps the focus on regular survival play while still leaving room for fights when you want them.
There is Colosseum PvP too, and keep experience plus keep inventory stay enabled there as well. So you can jump into combat without losing everything, which makes PvP a bit more relaxed and a lot less annoying for players who just want to mess around and have fun.
The rules are simple: no lag machines and no lava casting anywhere. If you like a more controlled vanilla-style server with a mix of PvE, PvP, and roleplay flavor, this one is built around that kind of play.
