Please note that it can cause loading issues if you set it too high. Also the Vehicles give a multiplier to this.
DefaultGroundSpeed=300

If you change the food consumtion to 0 you wont need to eat anymore. On the other hand some players wanted to make food more valuable so you can set it to whatever you want.
StartingFoodAmount=30
DurationBetweenFoodEating=25
AmountOfFoodToEat=5
AmountOfHungerToRestore=20
MaxAmountOfFoodAmount=100
DamageFromStarving=50
HungerPercentToAllowHealing=0.60f
DurationBetweenHealingFromFood=15
AmountOfHealthGainedFromFood=20
AmountOfFoodToEatWhenHealing=1

Basically you can edit the chance of what drops. Some PVE players might want to change those to 0 or at least PercentageToDropItems.
PercentageOfEachItemToTake=0.80f
PercentageToDropItems=0.70f
PercentageOfEachItemToTake_Food=0.40f

Those will allow you to pick up more ammo, but thanks to a hard limit on the station you cant craft more then the amount shown bellow.
BaseAmmoCapacity=(AmmoTypeName="CAGAmmoType_Pistol",MaxAmount=90)
BaseAmmoCapacity=(AmmoTypeName="CAGAmmoType_AssaultRifle",MaxAmount=230)
BaseAmmoCapacity=(AmmoTypeName="CAGAmmoType_Shotgun",MaxAmount=60)

Thanks to Kane Hart for that.
Higher or lower it as you like. This is the XP multiplier.
ExpScalar=1.0f

This should be the Time between events 7-9 days. I could not test it though.
SpacingBetweenEventsRange=(X=7,Y=9)

On the Events themself the TotalPointCostToSpawn=350 needs to be satisfied for you to get an event, so lowering that number might help as well to get more different events.
If the number isn't satisfied it defaults to slime attack or the first entry.

==Increase the amount of resources there is in a node (tree, gems, ore, element-x, etc)==
File: \SteamApps\common\GRAV\CAGGame\Config\CAGResourceList.ini

Find the resource name you want to change and change the minimum and maximums of AmountOfResourceHeld.

IMPORTANT! Don't exaggerate numbers because you need to empty a node to get the "rare materials".
I haven't found how to increase the amount of "rare material" drops that you get when you empty a resource node.

There's also a couple of other settings in her you might want to check. You can change respawn rate, how much extra a node holds in dungeons, how many spawns there will be, etc etc.

==Make the MultiTool more powerful==
File: \SteamApps\common\GRAV\CAGGame\Config\CAGWeapon.ini

if you've increase resource amounts like I told you above, this is very useful to so you don't have to mine endlessly before being able to get rare materials.

Change PerHarvestHitResourceAmount=25
There's also a lot of other settings here as well, like fire rate, healing and scaling for higher level tools but I would suggest you do not change the speed of this tool because it will put a bigger strain on the server. It's better to just change the power (PerHarvestHitResourceAmount)

File: \SteamApps\common\GRAV\CAGGame\Config\CAGDataObject_PlayerBaseItems.ini

All the buildings have nice names so it should be easy to find the one you are looking for.
Like: CDO_BaseStorageBin

Each buildable Item has a line:
bCanBeDamaged=true

If you set it to false you can't damage this item anymore, but the "Self Destruct" button still works.
Now keep in mind that not all items have that button and that you can be locked inside your base.

Now we only need to get them to give us the "Self Destruct" button on everything and to allow admins to press it too regardless of ownership.

I hope with those we can see more different servers pop up.
Can't wait to see a PVP server where you loose everything on death or a PVE server where you are save to die.
Also Food shortage servers where you need to go hunt for food because you will loose a lot of it.
