If Mercury 42's World's Will had been a simulation game player, he would definitely have been the kind with terrible skills and awful taste.
He had started by playing single-player simulations, taking perverse pleasure in killing off his own "simulated creatures," basically ruining his save file.
Then he discovered that his game actually had an online mode. By the time foreign enemies attacked, he no longer had any troops left to use.

You attack and I can't stop you? I'll pause time, cut off your reinforcements, and devour your vanguard.
Not enough population? I'll accelerate time and multiply those surviving remnants dozens, hundreds, or even thousands of times.
Can't raise the birth rate? I'll directly alter the population growth rate—mature at three, give birth every five years, three to ten children per birth.

"Even He must pay a cost. The accelerated time should be three to ten years, and once He enters that state, He will most likely fall asleep. The only question is how long He'll sleep."

"...Can this period be extended a little?"
