We have a lot of things in the FO Universe that we have to interpret from the info we have, and that's part of the fun. I never knew for certain about the robots and the soda machines, but I thought that, since they are the ones that are least affected by the situation of the world, they just follow programming. I read the food thing in a thread long ago, and that makes sense since we eat prewar food and don't die. I had no idea about the drugs and stimpacks since sometimes you find them in locations out of first aid boxes and they have obviously been there a long time. It would be cool if we had 'aged' ones that had depleted effects.
Finally, class act for apologizing, that's almost unheard of on the Internet and very cool of you. I normally tend to take things very laid back, but for some reason this one thing gets under my skin. I know it shouldn't, but it does.
The stimpak and soda machine things I just made up for myself; I assumed other people reached the same conclusions so thanks for the confirmation. The edible food I assumed was a deliberate developer's joke.
Oh, and not to get all Hallmark, but thanks for accepting my apology. I try not to say anything on the internet that I wouldn't say in real life, you know?
Someone should start a thread asking for fan theories on the mysteries. Think it would fly?
