I have to say I've been stepping in and out of SWG the last few months and I've been having a good time. Recently returned from 1year+ vacation. Transfered one char from wanderhome to starsider, and oh man is that place swamped with people. Always something going on, getting invited to heroic instances, etc.
However, the char that remains on wanderhome is still having a good time too. Wanderhome now is sort of like what summerschool in college was like. At first, it seems like you're the only idiot there, then after a while you start to same the same few folks around over and over and eventually you get to be friends and mayhem ensues. There is a crew of about 10 that I see all the time and we are having fun.
Also, in my opinion the game has improved much since the NGE first hit. Just an opinion. Hope that helps ya.
