Also I'm going to spend some time trying to think up good games that don't necessarily make sense now, someone help me out.
To change anyone's opinion, I think you need more than a "good game that doesn't necessarily make sense". I think you need to find a good game that doesn't make sense and benefits from the illogical/lazy world design. Otherwise, the game would be good despite poor world design, which also means a "good" game would have been even better with coherent world design.
To the point of "what do they eat?" I think it is a good point, but of course is one representative question of an array of like minded questions. Many people don't realize this and think it's just about eating. Thus that video should have asked a variety of these questions:
What do they eat?
Where do they sleep?
Where does their power come from? How do they power these generators? Do they make fuel or collect it? From what/where?
What do these people do all day? What evidence is there that they have been doing this work for several years?
What common sense protective measures has this community erected?
Do communities that have existed for years or decades know about the other communities around them?
If there are communities in close proximity, what is their relationship? Do they fight over water, food, shelter, supplies? Have they specialized with one providing medical care in exchange for the others food?
What use could these people have for new creatures in their environment and are they utilizing these opportunities as real communities would? (ex. gecko skin rugs, kitchen knives made from Deathclaw claws, scorpion armor or city defenses, domesticated versions of some of these animals - either for food, transport or warfare).
Before you suggest, "I just play to have fun & don't care if any of that is explained." Let me suggest you choose to care. B/f if none of these answers are either explained in game, then this games quests will be much crappier.
Quests where 1 community asks you to undermine another's power supply or defenses can't be implemented, or have no rational purpose when implemented if:
1) they communities don't know of each other & some relationship hasn't been established.
2) if communities don't have things like defenses, power supplies, or other resources to destroy.
So by making communities that have all the components real ones have; then players have a much wider range of ways to affect those communities, allowing for superior quests and for superior quest resolution.
