Having been a big fan of BW games since the late 90's I can say that TOR stands out as decidedly unlike BW. I smell that hand of EA in the background trying to $$$. This game is probably going to end up being a huge disappointment. I think there are two factors here.
1. BW games have always focused on story line. MMO players from what I have seen, and this in my first MMO really don't care that much about story line. The result is a great number of people rushing to 50 bypassing the story and then being bored. Frankly since I reached 50 with my first char I have rolled some new ones. 50+ is freakin boring if you are a real RPG fan.
2. Maybe TOR really has more RPG fans than EA realizes. I know I get real tired of the "your mom" and "you're gay" nonsense in chat. Ignore? Sure I could but then if I want to be social then what. Unfortunately the social skills of most of the players is lacking. Maybe its cause I am 55 but learn some freakin manners and boundaries. In person I would have broken a bottle on a lot of heads by now, or just wised up and stopped going to that bar, e.g., cancel my sub cause it just ain't worth putting up with butt toast slices.
3. The original server expansion was nerfed. It should have been far fewer servers coming online. It should have been free transfers for folks that wanted to escape that insanity of hyper packed servers and actually try and role play or be social. So a lot of us, like me, rolled new toons on new servers but eventually had to go back to our old servers as the new ones died out. By then the old servers were less populated and some of us just gave up and cancelled subs because after all we are doing this to have fun and relax.
4. What killed this game was corporate mismanagement probably on the EA level. The WOW fanboys were only here temp. They were gonna leave at the end of the first sub cycle, e.g., 3-6 months, e.g., March-June. When did sub numbers plummet? They should have just held fast and waited out the first wave but they expanded, too fast and too soon.
5. I love this game. I waited years for it. I am so disappointed. I will keep playing as long as I can get some fun out of it but I doubt that it will be more than another 6 months.
6. The only thing that will save this game is EA remembering who the customer here really is. Its the folks that played and modded KOTOR and their younger siblings and children. Its the folks that hung on playing Sith Lords. Customer service starts with realizing who your customer base really is. EA has lost track of that with this game and in the end that is what really killed it.
