Inflation comes from both sides: The gold you make, and the gold you spend. It's easy to say "But that item was only 10,000g in 2004!" while it's more difficult to understand that in 2004, that amount of gold took
months of daily posting to gain.
I will admit, I don't like that regular forum posting earns you so little compared to playing the games. It is no doubt to get people interested in the games, but I still think of Gaia as a forum, and as such feel a bit sad that foruming is so undervalued by the gold system.
That said, I see a number of items worth around 150k on your wishlist. One or two is 50k.
One is 15k. 15k can be earned within one day of playing zOMG or Booty Grab. I do understand wanting items, but if you are
asking for a 20 million gold item then you shouldn't be surprised that it is somewhat difficult to achieve; that's a bit of a life lesson.
