I hope that's a joke.
Anyway, Elite Force remains one the best action oriented Trek games I've ever played. The expansion pack adds the ability to simply wander the decks of the U.S.S. Voyager and have some holodeck fun as well.
Some talented fans created amazing mods for the game. My favorite one let you explore a TOS era starbase, and the ships being serviced there. The levels were so large, you could spend a couple weeks exploring it all.
