When does Cave Story take place?
Well, I have an answer to that question.
It won't be too long from now that we have rescue robots, saving our lives in dire need. But they are remote controlled, what if Quote is remote controlled. You control Quote in Cave Story (duh.) but notice how it treats everything as third person? I can debunk this with the fact that the game says "You" quite a bit.
It's clear that we don't have magic in our world, aside from 4Chan and Noxid. So Misery and about 80% of Cave Story wouldn't work... In real life. Consider we live in a world that has magic other than 4Chan and Noxid, Would Cave Story be possible? It's clear that Ballos uses "Magic" to allow the island to float. Or we could create a huge magnet levatator and mess up the atmosphere to get a floating island in real life.
About robots, we are going to be seeing them within the next 20-40 years. So around 2080-2100 is when we'll see Cave Story be semi possible... Or atleast Quote. Now if we lived in a world with magic, It would be even less time from that , I estimate about 2030-2050 if we had magical abilities here, sadly we don't.
(On a side note: Anybody else here hyped for Splatoon?)
