I played for a fair bit longer than I do most MMOs, but... it got to be too MMO-ish for me, with too many different powers and abilities that you have to constantly juggle. I know that kind of thing is a draw for a lot of MMO players, but I've never been big on MMOs in no small part because of that gaming style. I really enjoyed the space combat at the low levels, though, except for the 2d nature of it - but to this day, Bridge Commander remains the Star Trek spaceship simulator of choice for me.
