Gamedata in Ark - What is it for?

Hey guys,
I am trying to get an overview over how Ark works and I get the whole GameMode and GameState story, but what is the GameData for? As far as I know, you normally use it to safe stuff, but I think its working differently here. It also seems to be a data only blueprint. All in all it just looks like a variable collection to me. Can someone explain this class to me.

Also why is no GameData referenced in the Team MapAreaSotf?

Thx in advance! Cheers!

well i’m not sure if i’m right or not but think of it as an index for the game to load what it need when charging the world.

so if you add / change an item you need to tell it to the gamedata so it load the good one.
