Survival on YCC offers a semi-vanilla survival experience, with the addition of McMMO and claims. McMMO offers a leveling system for various abilities such as mining and agility. Claims are done using a Golden Shovel (which you should start with, or can purchase at several places in the server). Right clicking with the golden shovel starts the process of marking your claim, it will give you instructions on what to do from there. Right-clicking with a stick will show the border of your claim or any claims near it. These two essential tools are all you need to manage your survival claims. Your inventory is shared with the factions world, so it's best to start off in survival until you've got some gear and cash. The auction house is your main economic tool when in survival. You can use it anytime to buy or list items and blocks. There is no listing fee, so you can basically use it like an ender chest.
Factions on YCC offers a semi-vanilla survival experience, with the addition of McMMO and claims. You claim the same way you do in survival as well as using the auction house. The inventory is also shared with Survival, the difference is in factions PVP and raiding is encouraged. Elysium and Valyria are just two of the factions in the world. Teams come together in factions to lead a raid on another team using what they can including cannons loaded with TNT. When you first enter the faction spawn you are encouraged to pick a faction as soon as you can or make a new one.
Creative on YCC offers a semi-vanilla creative experience, with the addition of plot claims. There are plots surrounded by sandstone slabs or cobblestone slabs. When the plot is claimed it is surrounded by sandstone when its cobblestone it means its unowned. In creative new players are given one plot to work with and ability to build on them, above them, and below them. Players are also able to view other players builds around the map. To claim the plot, it takes 200 from your balance, which is shared between the worlds, and typing the command /plot claim when you find the plot you want. If you donate you are given more plots to claim which you can merge together.
Currently, there are 3 mini-games in YCC, eggwars, skywars, and prison. Each mini-game gives the player a chance to earn money to use on the other servers. Skywars is a fight to the death in the sky with 2+ players with chests full of unknown items in between them. In skywars players vote for the time of day, type of chests, whether it be normal or overpowered, and even the color of their glass box. Prison is a mining based minigame with PVP allowed in all but one mine, players are given missions to complete using the tools they are given. In prison, you are given an ender chest to keep your important items safe. You also receive tokens to use in prison to buy powerful weapons, armor, and tools.
