The time to raise the value of the firewall is here. I haven't seen it go for less than 25k in a while now.
I also believe that all values should be in strictly credit form as to detract from firewalls being the /only/ main method of currency. The firewall trade has been getting a bit ridiculous lately.
Updated. As I dont play much anymore I haven't been updating this thread. This should be only a rough guide so people know roughly where values are/ were.
Also firewalls have been made the main currency by staff by making trading credits infuriating. Considering a giftcard which sells for 9.5k is worth the same as if not more than a firewall, we have no easy way to trade credits.
I recently got a 150k spree and due to the items low costs. It has taken over 10 trades. I needed a lot of gingerbread blocks and 500 is only 25k. Thats 5 trades seeming if you do over 100 in a trade you can crash the trade or get booted for standing in one place for too long.
Many people want credit trading back and for the firewall empire that has been created to not be as bad but that is not going to happen. So firewalls are going to continuing inflating a ridiculous rate and credit trades are going to continue to be tedious.
