* ProjectSWG is the first NGE emulator for Star Wars Galaxies founded on *
|
|
* July 7th, 2011 after SOE announced the official shutdown of Star Wars Galaxies. *
|
|
* Our goal is to create an emulator which will provide a server for players to *
|
|
* continue playing a game similar to the one they used to play. We are basing *
|
|
* it on the final publish of the game prior to end-game events. *
