The older games typically had things where you could choose to do things in different ways. FO4 has yes, no (which is rarely actually “no”, but instead “maybe later”), sarcastic yes, and “tell me more.” There is no agency, and the choices don’t change anything.
It being displayed like the older style is just graphics. It’s doesn’t actually make it function like the older games would have, where you’d actually get to make choices.
Yeah, an asteroid detection and diversion system makes sense for a society. Those odds aren’t that low and the cost isn’t that high (and the other benefits it provides may may it regain its cost in value). It doesn’t make sense to prepare for a black hole hitting Earth and wiping us out though, for example. The cost would be insane and the likelihood is effectively zero.
However, you as an individual shouldn’t waste your time making an asteroid detection and diversion system. The cost is way more than you can afford and the likelihood is very low compared to events that could happen at any moment. It’s a waste of your resources and time to consider. Preppers are working as individuals usually.
