I wont speak for anyone but myself and this is why I stopped playing. Take it for what its worth.
1. WoW in space. Interface is fine but a Tank/Healer class cookie cutter has been done. And done.And done......Shooting a boss with a blaster at point blank range. SWG had that.
2. Get back to the Story. The storyline content was as always in a Bioware game, superb but I had to spend hours just to get from one side of the major storyline to the next killin 0/30 things over and over and over.
3. May the Force be With You to Kill that Thing and Stuffs. Voice overs were great but I dont need 1 min of dialogue to tell me to go kill 30 stuff-a-wompas. Way too much of that.
4. EA. I love Bioware I really do. I also HATE EA I really do. I suffered thru the Warhammer Online launch. Great ****in game with ****-*** deployment and marketing. Who gets that ****-In-The-Face award? You guessed it. EA you have ****ed up every MMO you ever touched or accidentally breathed on dating back to Ultima Online. I would crown you but in this case SONY beat you to the punch with SWG. I mean HOW can you **** up a brand like Star Wars. Unless yer George Lucas of course.
In closing, this in no way should be read as a criticism of the individuals who did their best with what they had only to be LAID OFF. You guys and gals worked your butts off and there are areas of the game where your passion bleeds thru. Take it as a blessing and move on to the next project that hopefully EA wont throw a bajillion dollars at to buyout. To quote Vince Lombardi, "I dont blame you, I blame the guy that hired you."
So there are my reasons. Agree or disagree thats the readers choice.
