The gameplay is unfortunately depleted too quickly. After a few days one gets to realize somehow to have seen it all. Too many missions to very similar. There are here and there on a mission which is really entertaining, but they are-perhaps at least to this point is an absolute rarity in this direction still something ...
The PvP is not wirlich unterhalsam because you get the impression this is the Klingon side over powered and if you can you really as Starfleet 10 Gefächten 2 times to win lucky. The ground-PvP are ways unfortunately no better.
The potential for the Star Trek game has been, at least at this stage, not even rudimentary angekrazt - which is a shame.
I can only advise you to get in JMD. STO plays first a buddy key and thus get an impression even free.
