Aside from the first two small capital ships that jumped the gun and engaged the battleship, when the fleet moved in the Conqueror basically became weaponless after a few vollies rendering the ship worthless. 2/3 of the video is a stagnant ship being used as target practice from what I see. I'll give one caveat. The use of half slopes in front of the windows is a nice touch. Other than that, if your intent was to showcase the battelship's strength, I'm thinking it missed the mark. Resources lost were essentially 2 destroyer type vessels and minor damage to frigates vs the loss of a battleship class ship.
Beware the leviathan, it swims in the deep! That was awesome, I wonder how other starships would hold up? Say BS Galactica or a newest Manticore starship (Honor Harrington)
Whats with people with their broadside space ship ? You can make your ship cover alot of surface area at the front and put all yours guns there since you are not planning to go side by side another enemy ship like in a marine ship battle.
