SWG did a lot of things right, and lot of things wrong, mostly due to the fact that LA and SOE did not listen to the established player base, but instead listened to a small vocal minority that , coupled with LA coveting the sucess of WOW, brought about the NGE (and the most hated of all classes..the ever cloaked spylol).
The game still had life in it, and could still go on. In the six months when they announced the sunset, a number of things we all wanted for years were added.
Atmospheric Flight - along with Air combat and Ground /Air, Air/Ground combat
Improving the GCW to make it more meaningful.Too bad they did not fully put out GCW2 befor ethe end, but what other game would a dev team still be tossing out enhancements as the clock begins to strike midnight?
Neither Trek Online nor SWTOR offers the big package that would keep players engaged for as many years as SWG did. But ...SWTOR is still a young lass, and it has the potential to be a great game, given that EA and LA give BW the opportunity to fully explore this games full potential as a long-lived revenue stream has to offer.
Succeed or fail..its up to them.
