Since some of you guys are quite familar with modding/changing the binary version of the game, why not work on the real one? It looks like AGE/Gamigo is looking for Shaiya devs:
They are looking for developers in general, but most likely not for Shaiya.
Shaiya is currently (and has been for the last couple of years) just a cash cow that will apparently get shut down soon. Most likely as soon as the few whales that still play leave the game.
