I am a total NooB when it comes to modding, that said, wanted to surfface an idea that at least in my opinion would make the game even more interesting.
Event chain triggered EPIC Mob Spawn
Requires a set of actions like # of becons activated etc (using already existing mechanics), triggers a marker (alien artifact), provides backstory and spawns a large scale aggressive set of mobs (LARGE)
Mobs drop rare elements or crafting mats
Better NPC animations
Same as many Skyrim FINS mods, can we have a pro build out better NPC/Creature animations and AI?
NPC driven fetch questlines, or just multi path quests in general
