You know what I'd like to see?
Well, I occasionally think that dreadnought battleships, notably big assed grand fleets of them, are just about the coolest thing in the world ever.
And while you get Hornblower in space a fair bit, I think there is room for Dreadnought! Britain, Germany and the Coming of the Great War, in space.
Which 2300 sorta is, but also isn't, but I like most of the background and so might as well use it as a basis for my daydreaming.
Firstly, no one refers to anything as a BB, BC, DD, HSBC or SMTV (nasty demeaning american invention. Battleships have names like Lion or Tiger or Warspite, and personalities and mythologies, not numbers). Battleships it is, and ideally the King George IV, or the British Grand Space Fleet.
Then, you need a weapon system. Some Big Guns to pound each other with.
Lasers are no fun, and don't have the range, and missiles don't work as you can catusha them off so you don't get the nice salvo effect.
So I was thinking of something that uses the stutterwarp core of the ship to initiate a short duration stutter effect in a projectile, that you the skips across reality towards its target and then, ideally, stops stuttering and deploys in to a cloud of particles that, with luck, impact your target.
Hence you need to predict the course and stutter pattern of your target, and can straddle a ship with good shooting.
Then you get a book on Jutland and do all this stuff about chasing around with battlecruiser squadrons trying to draw people on to the guns of the main fleets, and stuff.
Now, one of the nice things about Jutland in space is that you can have the battleships actually really shooting at each other, rather than half hearted indecisive engagements, in the same way that you can have the whole of a long period of history squished in to a little bit.
So you can do more fun things, like beat up minor alien nations to make you look good.
Although in fairness to all involved, British ships need to have a magazine explosion critical crop up more than it ought.
