SWG Pre-CU is the ONLY MMO game I think I'd ever pay for simply because its the only one that is any good.
While I agree SWG is a great game and they have one of the best crafting systems and is immensely fun to play. I would not say it is the only one that is any good there exists a game that believe it or not did not "NGE" their game to make it more anything but fun and immersive.
Final Fantasy XI online was and will always be one of my favorite MMO's to play i spent a lot of time playing both that and SWG and have loved them both for a long time.
So while i will agree that most mmo are replicated garbage designed to suck money out of our pockets for no more reason than to make gaming business money. SWG and FFXI I feel stand apart from that. I will admit that they sere designed to get our money but i think we feel less cheated because we got a quality product in exchange.
