A leaderboard or ranking system can provide an extra level of competition for players, as they strive to achieve high scores and move up the ranks.
Players may be more likely to continue playing the server if there is a leaderboard or ranking system in place, as it gives them something to work towards and strive for.
Also, it can encourage players to interact more with the server, as they check their progress and compare their scores to others.
Players may feel a sense of accomplishment when they see their name on the leaderboard or when they move up the ranks. This can increase their enjoyment of the game.
A leaderboard or ranking system can be customized to track a wide range of stats, such as kills, deaths, arrests, or any other metric that you choose. This allows you to tailor it to the specific needs and interests of the players.
