Personally I find every faction kind of the same. In the long run as you get to the higher levels, it doesn't really matter what faction you chose in my opinion. However, I did enjoy the Rom introduction since I started it after a break from STO, came back when I got the mail about the new faction, missions and such.
I hope they keep updating the game as they have done so far.
Also, what was the name of the trekbbs fleet? Would be interested to join.
