1. Duel Wielding-it would be cool to have duel wielding pistols/laser pistols etc, even duel wielding Power fists would be sweet
2. Renting out places- lets say for example i go to a place like Tenpenny Tower and go on a killing spree. no body but me is in the building. why not be able to claim it yours? you could rent out the rooms to travelers and passerbys that need a place to sleep. its a good way to earn caps.
3.Stealth/Blending in- Lets say you dress in Raiders armor or Enclave armor. and you walk by them. you shouldnt get attacked, at least right away. make um think you are one of them.
anyways, there are a couple ideas. let me know what you guys think
