EA has announced that as of Feb 1 SWTOR only has 1.7 million active subs, which amounts to a mere 85% player retention rate. Obviously most of the folks that have tried SWTOR can't stand it. After the first six weeks, it seems that Star Wars the Old Republic is an abject failure.
In all seriousness, I'm really glad to see that SWTOR is off to such a good start. It remains to be seen whether the game can maintain this level of success in the long term. But it's also obvious that the great bulk of players didn't rush to the cap and cancel their subs in the first month, as some have been predicting.
I personally have hit the ripe old age of 40 on my main, after playing nearly every night in January. I don't know that I'll be taking 8 characters to the cap to see all the storylines. But I'll certainly play up at least one Republic character after I finish playing the Empire side (they get a completely different storyline and a few planets that the Sith don't). That will get Bioware at least a few more months of sub time out of me whether they manage to iron out a decent endgame or not.
