So I got this idea from someone else, but what if every ship, or, at least, ships beyond frigates, had the Vast Bulk hull mod (the one that massive ships like the Derelict Mothership have, that divides them into multiple parts) making what you target way more important. So, you could permanently disable a ship's ability to move freely, by destroying the engine area, but it'd still be able to shoot at you. This, I'd think, would make fights a lot more interesting, as well as realistic, as if you just shot up one part of a ship, it shouldn't make the entire thing explode, it would just ravage a single area, making it useless. There could also, maybe, be ships or weapons that can repair pieces of other ships, so that you could, for instance, repair a capital ship's engines so that you can retreat, or push an attack that was stopped by a flank by your enemy.
I just think this'd be a cool new mechanic that could really expand tactical options. I'm not a modder though, so I don't know what amount of work would be required to do this, and what it takes to make a ship with Vast Bulk, so I'm just suggesting this to any modders out there that also think it's a good idea.
On an almost unrelated note, are there any good guides out there that explain how to make new ships and, in particular, ships with Vast Bulk?
