Well both me, wife and our two closest friends have been playing STO since beta.
It depends what your looking for, if your in it to power game and max to end level you gotta realise wow and all the others didn't have end level content in game at launch.
If your looking for An authentic ST style game where you can visit DS9, explore strange new worlds, customise your bridge officers and ship, go to alot of the iconic areas of the ST universe and generally have fun it is fun
Best fun we have had in an mmo for a very long time and the launch although bumpy is no worse than most other mmo launches.
Its different than most other mmo's as in leveling isn't a focus, leveling brings you better ships and weapons etc but you don't haveto grind and its casual play friends as in you can log on for 30 mins and feel as if you actually did something.
Final comment, as a core group we four have been playing pc games since the zx81 (remember typing the gaming in from the sinclair magazine) to every genre since and this is one of the nicest casual fun games aslong as your not focused on end game power gaming
