Star Wars Galaxies has arrived in retail stores today, as scheduled. However, our attempts to log into the online servers have so far been unsuccessful. LucasArts had told us that the game would be live early this morning, but a post to the official forums by the game's community relations manager has confirmed that there's a hardware problem with the subscription servers. The post says that LucasArts expects to resolve this specific issue quickly.
We'll have more updates on Star Wars Galaxies soon.
