Some natural events would be a perfect response to this request @Moderators.. Such as a volcano that erupts, but not too close to player built structures.
\\ Volcanoes would erupt on higher lvl locations such as naturally high mountains providing a lava pew that can be mined for precious materials including gold and gems and iron. You can even be providing a warning that a volcano is about to erupt nearby and you are in a potentially dangerous area. Volcanoes can petrify trees making them give you coal instead of wood (that would be completely awesome.
\\ Lightning storms would also be cool. They can electrify zombies and make them have special (unknown) features (to be determined by you)
\\ Holiday events are possible, just not in the same aspect as ark would be.
Say for example, every 365 days the game would provide its Christmas Event, (Santa's slay would drop an airdrop off directly to you providing a lvl 600 gun and a full block of ammo for it), During this day, each trader could have special items available.. ie. Full blocks of Nitrate or gunpowder available for purchase at a discounted price. All basic items in trader could be 50% off for christmas events.. Besides, not too many people make it 365 days on a server.
The game could also use more customization at main menu or pause menu.
It would be nice to have a mode that zombies never run like all star athletes but also not be completely the easiest mode, an option to make them harder to kill or hit harder.
An option to restart a world/seed in case something bad happened and you dont want to completely delete the world.
An option to refresh the traders to fix any potential bug that is preventing people from using them.
An option to build a manual save point. This is incase of a major bug that erases parts of your base and cause you to lose everything--1 save slot is acceptable
---There can be limitations on manual saves too, ie. 1 save per week maximum.. This will prevent people from trying to use it for exploitation purposes.
An option to control the size and amount of water bodies provided on map upon creation.
An option to attempt to control the average biome around hub city (heat control knob) or something to that nature.
Make keystone days a thing.... Day 100, 200, 300.
There are so many things this game has the potential to do that can trump ARK, screw ARK
