I was looking for a forum thread of implementation ideas. More based on the building system. But while I read this I want to put in my two cents. ^^ (🇩🇪 idiom "Give my mustard"😂)
I read of many problems for overpowered guns. But don't forget that there may be overpowered defense systems, too. Of course you can use BFGs for defense. I mean rather shields, sensors and a secret service. While shields will also need much energy, but let's say the biggest one is strong enouth for lots of BFG impacts. They make it possible to strike back effectively. Also BFGs can appear on the sensors while routine scanning a ship. Showing a high energy usage or if hidden/deactivated a disproportionately power generation or power storage. When we talk small ships with nuclear weapons there will be a level of radiation and sensors trigger alarms. This may not work if the sensors are near to own nuclear weapons and so on. All of this may lead to using security protocols. You know.. Political and military squabble. ^^ hm.. BTT: Modular Weapons sound interesting. There are many possibilities of weapon systems and NQ read our ideas. I'm sure NQ will do a good job. They will balance it.
