Is/will there be an option to be neither Federation nor Klingon empire? Like just be a trader or something.
Do you hate both factions, or do you just not like fighting? I think they are planning on adding the Romulans eventually if you don't like the Klingons or the Federation. If you don't fighting, but like selling stuff, you could try Lemonade Tycoon, it's free on the internet, because Star Trek online doesn't provide many exploration missions without having to fight also.
Even though you do have to take a side, you do not necessarily have to fight. You could hang out at base all day and breed tribbles, and try selling them to make enough money to buy food for them. Probably won't be sucessful.
