I'm really enjoying the game. The armor and weapon modding is a great addition. I'd love to see more of the base clothing mod-able. For instance the only clothes that can be currently modded for me is the vault 111 suit. I'd like to be able to add the buffs for energy and radiation resistance to the Road Leathers or the other items of cloths you can wear under the chest, arms, and legs. Also modding headwear would be great. It's should be simple since those mods do not show and won't present any clipping issues.
Can't wait for the new GECK. That will be the very first mod I create.
