I personally would really like to see a new mini game with 2 big teams facing off against each other, specifically, Capture The Flag. I remember one of my favorite old Java edition servers (that got shut down like 5 years ago) had a really fun capture the flag mini game. It wasn't like any other server capture the flag. It would feature 2 teams of big players, they would all spawn with the same stuff. You didn't get stuff and then fight, because you couldn't break the map. You would just go and attempt to catch the other team's flag and retrieve it to your own base. It was simple, straight forward, and I really liked to play it. I also think that a new big PVP game would attract so many new players to the Mineplex server.
