Initially a lot more, because of the shock and the will to ba back to my world, among humans, living the life I’ve been living my whole life. I wouldn’t want to die alone in what looks like an unexplainable minecraft world.
I may, eventually, reason that for such a thing to happen bigger forces must be at play, so I may just willingly try some form of suicide out of curiosity, so in such a state I would be a lot less scared.
Depends on how hard performing tasks are. Can I punch trees to get wood, it doesn’t hurt like hell and doesn’t break my fists? Can I dig through the earth quickly with just my bare hands? Can I construct a dwelling relatively easily? If yes, then I think I’d be ok after getting over the initial shock of “WTF?”
If we’re talking real world physics, then I’m probably dead the first night.
“High in the North in a land called Svithjod there is a mountain. It is a hundred miles long and a hundred miles high and once every thousand years a little bird comes to this mountain to sharpen its beak. When the mountain has thus been worn away a single day of eternity will have passed.”
In the real world I very rarely jump down multiple meter drops, am seldom asked to fight zombies or skeletons, and have a lot of supporting infrastructure that ensures that I am fed regularly. Minecraft has such a lot of ways to die.
