Might be just a silly conspiracy, but sometimes I do wonder what group of players are coming up with the prices like they do. When the 20mill mounts were added to the game that suddenly the other mounts that weren't even worth that amount skyrocketed in price. Night Pegasus for example wasn't always 11mil on my server, and those mounts from Eureka jumped up like crazy as well.
Part of me is like "wow I can make gil from this" , but at the same time "this sucks for anyone that didn't get these mounts back in the day when its only worth like 2-5mil".
