If the World Consciousness of Mercury 42 were a simulated game player, it'd definitely be that lousy type with no class.
It first played a simulation single-player game, deriving perverse pleasure from killing off its own "simulated life forms," basically playing it into a corrupt file.
Then it discovered that its game was actually the online version, and when foreign enemies attacked, it had no available troops.
"Can't beat them? I'll just cheat."
So, it chose to activate the cheat codes.
You're attacking and I can't hold you off? I'll freeze time, cut you off from your reinforcements, and take down your vanguard.
Not enough population? I'll speed up time, making those Dead Survivors increase by tens, hundreds, or even thousands of times.
Can't boost the birth rate? I'll directly modify the population growth rate, making them mature at three and reproduce every five years, with three to ten offspring.
