While I know that the following things I am asking for may never happen, the one thing I do know, is that never asking guarantees this:
The first thing, is for map making itself (something I like to do), & it boils down to the ability to dictate what is spawned for a planet, namely the number of resource asteroids that spawns for a gravity well (both neutral & colonizable), & the ability to force a neutral faction to spawn for a planet that is not owned by a player (such as militia or minor factions).
currently, the galaxy forge only allows the spacing of pirates through the use of a galaxy template, but trying to spawn a planet owned by militia requires notepad finagling. There’s also no method to force how many resource asteroids a gravity well possesses without modding game files. For maps that make use of minor factions, it may be possible to have a map go through a check where the game determines if the map uses dlc resources, & if so, locks the map from use in a similar manner that the provided dlc stock maps are (I am reaching with this, I have no idea if this is physically possible). The other option would be to have the map stripped of dlc components during map load for the hosting player if unowned)
The second thing, is what used to be a feature many an update ago: the ability to choose how “random” resource asteroids are for an individual game session in the game settings. This option had been removed in favor of an “economy rate” option. For this, I suggest 4 options: default, low, medium, & high
default would treat resource spawning as it does currently, where the asteroids could be anywhere from the minimum or maximum amounts based on the settings of each planet (ie the radiation storm gravity well would have at a minimum of 1 metal resource while maxing at 3, while crystal would be anywhere between 0 or 2 resources)
low would aim for the minimum amount of these settings (high being the maximum), with medium being the middle amount (rounded up or down)
Alternatively, it could be three options: default, minimum, and maximum
While I know what I am asking is essentially a shot in the dark, I hold some hope that my request finds an ear & leaves an impression on more than just echoes.
