Is LG looking for any help on the project? I have been looking for a game like this to work on (pbbg/fantasy theme etc).
I am not very familiar with Silverlight but can write in c#, java, as3, python etc.
I also began a flash based game VERY similiar to Perenthia that I think you would be interested in looking at what we did... here is a screenshot of the inside of a shop, the items are draggable to the player to purchase. It is based ontop of the smartfox server platform (java) and as3/flex for the client.

Also, the artist who did the work in that Screenshot would probably follow me to this project if you guys needed one.
