Really?! That's what you found wrong with this? Lighten up it's probably a lot less offensive than some of the achievements we've seen in game and you know it besides it was an example and within SE's proven track record for humor. Anyway to answer the on topic question above Stellazio were key items in ff9 there were 12 you found them hidden around the world as you traveled and turned them in to an npc in Treno.
In this game Treno would be a good comparison for The Gold Saucer, it was a pleasure community for the rich which also contained a slum for poor refugees, it was a gambling town which also hosted the games card game tournament events. As you turned in these stellazio items you were given a number of items including potions, gil, and rare armor's and weapons for turning them in. My idea takes this idea and makes it a year round event with monthly changing rewards, and infinite replay value which rewards players who play without taking breaks while not punishing those who do take breaks. Join in at any time and if you miss a month pick it up next year, unlock the year's achievements and you can purchase a month's items you may have missed as a year round item.
