Really? Care to elaborate more?
Well I haven't played that long yet, but so far it's all good. The character creation system is the best of any MMO I've played. It really is possible to not have everyone look exactly the same. You can make your character one of the established races or start completely from scratch and make up your own race with its own backstory. After spending a couple of hours fine tuning my character, I really cannot go back to the WoW or SW:TOR character creation system.
Some people said the ground combat is bad, but I don't really know if they are talking about the group dynamics or what, as I cannot comment on that. But as far as the mechanics, it's actually pretty innovative. You can switch between a "RPG" mode which is just your standard MMO combat and a "Third Person Shooter" mode where it's kind of like Mass Effect.
Space combat is definitely where it's at though. You really can do nearly everything you see in the show. Diverting auxiliary power to aft shields and all that jazz. You can fly pretty much anywhere you've ever heard of in the tv shows and movies - Alpha Quadrant, Delta Quadrant, the Cardassian sector, wherever you want.
I just love the variety of being able to beam down to planets and space stations or travelling in your ship. The sense of scale is really awesome.
Lastly, I believe they actually got Leonard Nemoy to do narration. Correct me if I'm wrong someone, but it definitely sounds like him. Each time you go into a new sector, he narrates some background about the sector and even references things like the '09 Abrams movie. For a Star Trek fan like me, that was simply awesome.
EDIT: OH yeah, I forgot to mention, virtually EVERY single ship I've ever heard of is in the game. There are also many ships that were designed just for the game. The only ship that I was disappointed about not being able to pilot was the original Phoenix that Zephram Cochran piloted that resulted in first contact. I know that ship didn't have weapons, but it would be an awesome "fluff" ship to just fly around in. I mean it's basically a missile with two nacelles, but I just love the design for some reason!
