Do not recommend this game. I am a lifelong Star Trek fan, and I even was a Star Trek online fan for quite a long time, but Perfect World killed this game. It is but a shell of what it used to be. They want money for every little thing. People will argue against this point, saying you can convert dilithium to zen and what not so no need to spend real money... DO NOT BE FOOLED. It is a deception. If you were to go the dilithium to zen way to purchase new ships and stuff IT WILL TAKE YOUR ENTIRE LIFETIME. It's capped at 8000 Dilithium per day, you would have to spend every moment playing grinding toward your goal accross multiple characters to get what you desire.
The Delta rising expansion made the game so much worse than my above description even. Ships you already bought and paid for, now require expensive money bought items to be upgraded to be kept up with the new level cap increase. They decieve you by saying these upgrades are optional and not neccesary to play, but it is a lie. You will be a scrub without these upgrades. No one will want you on their team in any serious content if you run around without a properly upgraded ship.
All in all the only good part of this game is the roleplaying aspect in it. Character creation is pretty immersive. Biographies are possible, plenty of social map and an active community. That is the ONLY reason anyone should play but the game itself? It's horrible.
