No no no no no no no no! You got this all wrong.
It started when Stefan wanted more money. Classic was failing and Era, well.... was boring.
Since his beloved Classic was already far along the path of destruction, he decided Era was the way to go. So, he invented the crab, a sort of ugly creature with claws and stupidity programmed into it's brain.
Next he used his godly powers (also known as Scripting) to give this crab life, in which he made it evil.
Finally, he used the random factor to make it randomly spam whenever dirt was dug. Because, he was bored as "heck" and wanted to be stupid.
Than he invented players, with his idiotic scripting and such, and made the revive in these annoying things called Hospitals. You see, he still needed money. So he made instant revive-on-spot potions (which, by the way, make no sense whatsoever if you think about it). Of course, you had to pay for such 'luxurys' as not being dropped off a rapist hospital.
So he invented the Shop, in which he added a way to buy money. (Wait.... what? Buying money? Oh screw this. It makes sense in someones head.) Than, ......? and Profit!
Thus born Era.
