Do you remember the moment you hit 1 gold for the first time? I do. I was killing mobs in Ashenvale, vendoring Light Feathers and other various trash drops. It was an epic moment. That first piece of gold felt like so much money.
It wasn't a lot of money, of course -- it just felt like it. But still, it was worth a heck of a lot more than one piece of gold is worth today. The reason: Azeroth suffers from a constant state of hyperinflation. The purchasing power of 1g is always falling, and it's falling quickly.
Thankfully, though, you don't have to stand by and be a victim.
