I see the appeal but that appeal doesn't apply to me.
They took the Metroid out of my Metroidvania and replaced it with Dark Souls, and that just rubs me wrong.
I like some Souls-likes (Elden Ring, Lies of P, and Lords of the Fallen reboot are some of my favorite games) but I don't like souls design creeping into my other genres that don't need it, especially when some of the mechanics are antithetical to the genre (looking at you corpse runs).
Eh, not really but kinda. The available recorded data for that information is scarce and not a complete picture. Some studies were done but they are centered on things like "expectancy of tenants/landowners" for example, not the overall picture. It's a complicated topic and I don't fully understand it myself.
Though, what I do know, is that through other methods of anthropological and archeological research methods, like examining bones, we are able to prove that people generally lived into their 50s-60s.
