A Towing Service: A third party towing service (owns their own tow truck) that offers feild repairs, feild fueeling services, or simple tow, that can be contacted on a specific radio chanel (not secured or encrypted, so yes you could be intercepted). Flat fee for all services: 300 caps, will to anywhere to anywhere. If you tow to their shop, they drive. If you want to go back to your own shack, you drive (so you loners out there, you have to go to their shop). Briinging fuel (200 sme or rotgut) cost extra. their tow yard is secured from PKer's and theives, but not lockpickers, BE WARNED!!!
Money: Make money territory-specific ish.
In the NCR, BOS, Sanf Fran, Junktown, and Hub you use Money (FO2 money). In Boneyard you're supposed to use Money, but there are a few merchants that will accept caps (at a slightly lower-than-par value).
In Redding, Broken Hills, and New Reno they take both.
In Redding, they also accpet Mine Script, but the only otehr place where it has any value at all is in New Reno, at slightly below par.
North of that line they only accept caps (maybe VC accepts money, but below par, or even issue their own coin).
Fishing: If you set up on a waterfront/river front site and have a fishing pole (crafted from 1 sharpened pole, 1 peice of junk, and 1 fibers, does not require a workbench), you can fish, catching fish based on your outdoorsman skill (above 100% you will catch something eventually, but the higher the skill from there the faster it will happen). A fish is worth +40 hit poitns, +1 radiation level after 24 hours. shoudl be fairly herfty as well, if you cook it the radiation wwill go away, but it also looses half it's healing powers. (This idea actually came from Aninal Crossing, which is what my sone was playing when this idea hit me.)
