I had an idea for a challenge run on fallout 3 where basicly, when you shoot any gun you shoot your caps instead of ammo. The challenge being ofcourse that you have to managed your caps especially on the harder difficulties and surival mode. With the help of chatgpt ive tried to play around with geck and fo3edit but i got a headache and gave up xd. But yea a mod where you use your currency instead of bullets and maybe an on screen cap counter to help you visually.
