I think it might be best to decide on what type you'd prefer to play (e.g. heavy cruiser, destroyer, submarine, etc) before deciding on class. That way you're not looking through hundreds of Clemson-class or Fletcher-class destroyers or some other variation of a ship class that was mass produced before you have any idea of what style of combat you're looking for.

Thanks for the link. Sorry for the confusion but I meant RPG class (tank, rogue, mage, support, etc.) rather than ship class. I get that subs are like the stealthy rogue-types, but beyond that I don't know the difference between a dreadnought and a battlecruiser. I was asking for a dumb-down analogy of types, but I realize it may not be one-to-one.

Combinations as in two ships merged into one?

Yes, I remember from the show (its been a few years) that two ship's could merge to fire some giant gravity cannon thing. I think there was also the issue of 'partner ships' and compatability, which I think would be a fun dynamic to include.
