All of them
I dislike how we have no highways. So highways that actually go from city to city or ‘just go’ would be nice.
NPC ai is always a thing. Currently NPCs will literally explode if they try to reload single-shot guns.
NPCs dont have a comprehensive way of changing armors. They seem most fascinated with splints when they dont otherwise need them.
And, as someboyd trying to mod the game and who sucks at lua, Im pretty frustrated with how rigid the system can be. I want stabbing damage from enemies, or Id like ant-sting attacks. Or Id want ‘vicegrip’ attacks. To give to ants.
