Sorry for the delay in getting back to you guys.
To my understanding (forgive me, I've been doing a lot of stuff recently and thus might have remembered some things incorrectly), due to the traffic on here not being as active as it once
@Digital had said that it wasn't worth the extra cost for features like the Marketplace, Game Directory and such. I'll message him and ask him to have an input on this topic as I don't want to speak for him.
Although on a more positive note, I am currently working on a replacement to the Game Directory in the form of a thread version.
Similar to what I had on Virtual Pet List, one for In Development and Public Games whilst both focus on RPGs/SIMs/Virtual Pet Sites/Mobile Applications. But it's not anything final yet, so it may not come to much.
