I don't really want to rely on humanity not digging through black orbs of evil and summoning a giant worm. Or, you know, some idiot going into the dungeon and then running through a city with the Guardian chasing after him and murdering thousands in its wake.
Or, you know, hardmode.
All games look "better than real life" if you only focus on the "fun" stuff. I remember back in the dawn of the internet there were guys going "Doom would be awesome IRL! Imagine using a BFG 9000 LOL!" Yeah, that sounds awesome. Except for the part where demon-like aliens turn the whole Earth into a wasteland.
