Megabases, I don't buy it.

Does anyone know where this "Megabase" concept came from in DST?

I don't understand what's so bad about building just a base? How much bigger is a Megabase compared to a Base? Can't a Base be the same size as a Megabase?

Is it just gamers that feel small in their real life and want to convince themselves they're doing something MEGA in some area of their existence? Is it just a Clickbait Buzzword to draw attention?

My base takes up the whole Oasis Desert, but I never thought of it or referred to it as a "Megabase"
