You should make a gamemode surrounding a group trying to kill a boss. It can either be like where theres 2 teams trying to gather resources(like walls) and 10 minutes into the game, it teleports them to an arena, Now this part can have 2 ways, it can either be who ever kills the boss, wins it for the team, or which ever team kills their boss first. I like the second one better but it's an idea. But a boss minigame would be a big step for a new game!
