I think that having groups would make the community reach out to each other. Having groups for games like eggwars and skywars can have leadeboards. The wins would be added up in each mode and would all have leaderboards for each mode. Lets say i have 5 people in my guild, we all have 25 wins in duo eggwars for example. That would add up to 100. The top 50 guilds would be featured and you should have your guild name as a customize able prefix in game chat. I am not sure what the maximum amount of players in a guild should be but I recommend 25 players per guild. This would add a whole new sense of community to the game having people to always play with.
