There is alot of neat things FOOK2 added.
Weapons are not so important as they won't have iron sights plus with the weapons NV, FOOK and any other mod more then make up for it.
What i really wanna see is unique armors they made for important NPC Moria had a tool belt [ its in Tailor maid as well so you can just give it to her with that], and Riley's Rangers had unique gear that showed their class and also a few little nice touches here and there.
The other big thing is their follower Malcolm I really liked him, had his own voice actor and commented about your surroundings, even gave you advice similar to Sunny. I'd love to see him come back they had others a girl named Deshia but as for as i know she was never voiced so i don't care so much, they also had a cyborg dog named K-9.
