Last question, is it just a crapshoot what prefabs you end up getting in RWG, I've seen some really cool ones people have made and want to add them. Is there any surefire way to get them on your map or just generate and check command when you get in game
As Stallion says, there's no guarantee.
POI placement by RWG is basically a competition between POIs. Various factors determine how many opportunities there are to place a POI. A POI's "Tags" and the POI's size have the greatest effect. If the POI isn't Tagged, or isn't tagged something meaningful, then the POI won't get placed. If the POI's size does not match up with the size of POI makers on Tiles for which the POI is tagged, the POI won't get placed.
If the POI is appropriately tagged and is of a size that is supported for those tags, then the POI has an excellent chance of getting placed unless there is some other constraint. Obviously, larger maps have more potential POI locations. You can make cities more/less common. You can make wilderness POIs more/less common.
If you look in the XML file for that POI and tell us the "Tags" property and the "PrefabSize" property, we could provide better insight. For instance,
I downloaded the Central Station above to take a look. There is no "Tags" property, which will keep the POI from getting placed by RWG. The POI size is 100,28,100 ... so it needs a 100x100 footprint.
To get it to spawn, you will have to add a "Tags" property. The only three vanilla districts that support that size are: Commercial, Industrial, and Rural. I suggest tagging it for Rural and/or Commercial, depending on where you envision it:
<property name="Tags" value="commercial"/>
If you tag it for Rural, then it may need some "driveway" parts added. You could also make this POI spawn in the Wilderness if you tagged it that way.
