The PoC updates may be focused primarily on the famous "Global Multiplayer Survival" game mode. It's also good that they want to implement other game modes like SkyWars, Hunger Games, etc. But they neglect player creativity. What I mean by this is that new players who are just joining the game not only seek to play Survival mode, but also seek to express their creativity in Creative mode. You can tell this by simply entering any map in "Private Maps" mode and seeing the people who want to build their structures, mostly new people and not people who have been playing the game for years. But what's happening? The problem is that people simply get bored of how repetitive Planet of Cubes is and abandon the game.
The problem is that Planet of Cubes updates have recently greatly limited aspects such as creating your own maps and exploring with your friends, being able to customize your own maps to make creation more exciting, etc. What I propose is that they revamp the customization options for private maps and make them more accessible to players. Some of my examples, so you can better understand what I mean, are:
1.- ELIMINATE THE FEES TO CHANGE MAPS FROM CREATIVE TO SURVIVAL WITHIN PRIVATE MAPS
I fully understand that the number of maps players can make can affect server maintenance, BUT ONE THING I DON'T AGREE WITH is implementing fees to change the map type. Aside from the fact that it doesn't generate any conflict between players, it's also very THICK-FOLDED of them to want to impose fees on things like that and use the excuse that gems are "easy and free" to obtain.
2.- Ability to open chests and interactable objects in Creative mode.
This suggestion may be optional, but if you have the opportunity to add Tools to Creative mode, you can also consider implementing this mechanic. It could also be useful for creating maps similar to Hunger Games or perhaps exploration and survival maps.
3. Ability to add spawn eggs
This proposal is primarily based on creating maps such as castles, coliseums, farm simulation maps, etc., but with the exception that there is always a limit on mob spawning in chunks to avoid server issues.
PoC, these suggestions are based on the testimonies of the majority of users I've seen giving their opinions about your game. I hope you listen to me and manage to add these things to your game, while also taking into account optimization. These are my suggestions. And first and foremost, good morning. Thank you.
