A Note From The Developers
June 18th, 2008
This is a special thank you to all of our beta testers who so graciously participated in our first two Quests. These were a major milestone in our development process and the information we gained from the Quests has been fantastic.
The Quests bring together many of the technologies and make testing them under load a reality. We thought we would share with you some of the more exciting results from our two Quests.
One of the most important tests we were able to perform with the Quest was the use of the trading engine. The award of the prizes used the trading engine and with literally 10's of thousands of trades, many of which were simultaneous, there was not a single error. Thank you all so much for making this test possible.
We also want to thank you for doing these Quests without the benefit of a map. However, we needed to do these Quests before we added the map to complete the tests. In particular we were able to test multiple simultaneous teleports from a room, multiple simultaneous teleports into a room, massive simultaneous click requests to move in a room to a location or to select an object, and large chat loads in a room. From this data we were able to reduce the memory requirements on the servers by over 7 times.
We were also able to test what happens when 100's of thousands of items are placed in rooms, moved around and then removed from the room and placed back in inventory, almost simultaneously. After analyzing the databases we are pleased to report that not a single item was lost. We did have 15 items which were placed in rooms we would have never imagined possible. One was a "pink couch" in an Audubon Wildlife Adventure room. We changed the code to prevent this from happening again and put the couch back in the person's inventory
Last week we re-factored our primary 3d engine which made it faster, more accurate and more stable. These Quests also allowed us to test these new developments, and again, everything went perfectly.
There were a great many more metrics which we collected, most of which are very mundane and boring, but because of this data we have spent the last two days making enhancements based on the information gathered from the Quests.
We hope the great prizes our graphics team created especially for these Quests show how much we appreciate your help during these beta tests and our heart felt thanks.
So, in the future, when anyone uses a teleporter, makes a trade, places something in their room, or even just goes from room to room, you can tell them that you were part of the Beta Quests which made this all possible.
We have a fun Quest planned for this weekend which should allow us to complete the cycle of development. The great news is that this means we will finally have a map and your hard work of trudging through the kingdom will have paid off! However, we will miss seeing the garden so full of people everyday about to go out into the kingdom.
Again, thank you all so much for your help in making this new world a reality, and thank you for your help in our Quests.
Your Development Team

PS. As an interesting side note, the bug which makes it possible to have different size characters after changing clothes or hair is the result of a single line of code. However, it seems that everyone is enjoying this, so we will leave it a bit longer. If you haven't experienced this bug, make sure you do before it is removed.
PPS. We also thought we should share with everyone a bug in the Audubon Wildlife Adventure game. The bug is that the last option in the multiple choices is never correct. So, on the second level, it is always the first choice. It may not seem like a lot of credits each game, but if you just play it consistently for an hour you will discover you have over 3,000 credits. This is because the game restarts quickly and because of the bug you can almost always make over 50 credits per game. The worst case is that you will end up knowing a lot more about our natural wildlife, not to mention being able to impress your friends with your knowledge of birds!
I have a friend on my friend list who is space_gas.
. Then sent another email to them thanking them and adding a suggestion, and received another personal email. Another friend sent an email and recieved a response back with correction made in game immediately. That's one up in my book!
