What to say about this game? It is not as bad as the reviewers are saying.
* It have a lot of bugs. It still feels like it should have been a beta.
* It has the most non-combat missions i've ever seen in an MMO. A lot (relatively) of missions is just "beam down, talk to a person, go to another person, scan something, done!".
* The most fun aspect of the game is ship combat, both PvP and PvE. If you liked Pirates of the Burning Sea for its ship combat (and didn't care much for the pirate theme) then you will probably like ST:O ship combat.
* It is pretty consistent story-wise towards Star Trek-canon.
* A few of the models and graphics, mostly the uniforms, ships and spacestations, feel a bit to non-trek.
* Some missions make federation "evil". Example would be a mission where you scout a planet for resources, but some aliens were there first. So as a Federation officer it is your duty to kill them and take their stuff! :O
* It is easy to earn money/credits in game, so unlike other mmo's you don't have to worry about mis-spending them.
I started playing Bridge Commander a few days before i started playing ST:O. I found BC to be very authentic to the Star Trek experience, but a bit boring in the long run.
