Thanks man, for both the congrats and the screenies.
And guys: How long did it take you go get to klingons? and to battlecruisers? Can you stay in space only?
It takes 24 levels as a Feddie to unlock Klingons, and Klingons start at level 20. Doing it like that was a dumb move, IMHO, but they are apparently planning it so you can play a Klingon right from level one ( I don't know if that's with or without unlocking them). If I remember right, their original idea for the Klinks was that they were gonna be PVP only, an option you unlocked later after you were more familiar with the game, sort of like LOTRO's monster play.
When I first tried STO there was almost no storyline or quest content on the Klingon side of things. Fortunately that has changed.
Ship wise, as a Feddie you start with a Tier One 'Light Cruiser' (Miranda, Centaur or Shi'kahr class or a kitbashed hybrid using parts thereof). Once you advance to Lt. Cdr (Tier 2) you have to pick your next ship type: either an escort (focused on agility and DPS), a cruiser (focused on tanking) or a science ship (focused more on buffs and debuffs). You're not locked in to one class by this choice and can get a different type of ship at the next tier, if you want. Rog, for example, had a Nova-class science ship as his Lt. Cdr ride, but switched to a tactical escort at Commander.
You can also buy additional ships with dilithium, which you can earn in-game.
Klingons have essentially the same setup, except you don't have to mess around with the Tier 1 ship (A B'rel-class Bird of Prey) if you don't want to. You start with a Tier 2 ship, I believe, and it can either be a BoP (agility and a 'battle cloak' which you can use in combat), a Raptor (DPS, mostly) or a cruiser (much like the cruiser's on the Feddie side with more agility and more forward weapons; Feddie ships have balanced weapons slots and tend to be best used as old-school, broadside-to-broadside type ships).
And no, you are not confined to space. Many missions have ground components, and there are ground 'war zones' for PVP and PVE.
In fact, you even get bridge officers you can take down planetside with you, and you can customize their names and appearance. To allow the same kind of variety the Fed side has with this, the game backstory explains how the Klingons conquered or absorbed a few less-seen Trek races (including the Gorn) and these races now serve in the fleet...and yes, are available to play as PCs as well. There's a lot of Orion females running around in command of Klingon ships.
Incidentally, what is one of the creepier missions I've ever played on an MMO is in this game and mostly ground based. Playable by both sides, too.
