They aren't for everyone. I realize that I would give another one a chance, but I probably wouldn't end up playing them for long. SWTOR didn't really execute perfectly, but as far as story goes, they did a great job, at least with the two that I've played. It's right where it should be now with a free-to-play option to try and attract some hardcore Star Wars fans who aren't into MMO's.
Which character did you end up starting, and what level did you get up to? I will admit the opening planets are pretty bad, you've got to give it at least two planets before calling yourself off it.
