Well, I've seen some very good ideas on this thread, as well as some ridiculously game-breaking ideas, so I think I'll try to collect all the good ideas into this post as a comprehensive plan for the implementation of nova bombs.
Nova bombs should take a long time to build, and require a dedicated and expensive manufacturing facility, and should have some serious risks associated with them
This is fairly obvious. I don't actually like the specific examples he gave though, because most of them had to do with the bombs randomly exploding. Conceptually, I don't like to think of it as a bomb per se, but as something that causes a kind of chain reaction in a star, therefore not being dangerous when a star is not present. From a gameplay perspective, this is justified by the fact that random explosions, or anything random, for that matter, create a fundamentally inferior competitive game.
Just a side note, if lunar bodies are implemented according to my model shown in this thread
, then only being able to make such a facility on a moon would be ideal.
Usage of the bomb should result in a worsening of diplomatic relations with almost every faction (although maybe there could be some factions/species who actually *like* the idea of destroying the galaxy, as in, like, its their mission in life, which would be add interesting twist to late game diplomacy)... in fact, if the majority of your own population were against the idea of using nova bombs, then you should also suffer a massive increase in unrest levels.
This is also right on. A nova bomb should be something that you use very few times in the very late game to take out a critical system. The battle in which the nova bomb is deployed may very well be the determining battle in a close game. Which brings us to the next point, using the nova bomb in combat.
We could say that the nova bomb is launched from planets, that would be cool. And nova bombs, being a missile travel at the speed your ships travel. You might as well say that you have to build a ship of type 'nova bomb.
Yes, that's conceptually very near to what I have in mind. The ship would essentially have one massive slot for the nova bomb, and nothing else, and of course this ship type can only be built at the special facility. The nova bomb can only target stars, and has a very short range, necessitating brilliant tactics, a large escort armada, or strategic timing when the enemy system is relatively undefended, all or which are very difficult and/or costly.
3: massive cloaking penalties for any ship carrying it. (if we actually use cloaking in the game)
Marhawkman has hit this nail on the head. A race with stealth bonuses and massive stealth technology getting the nova bomb would break the game. Therefore, nova bomb ships should have their stealth meters severely penalized, perhaps even permanently set to 0.
I've also seen various posts regarding what exactly should happen when a nova bomb is detonated. Since this should be a very rare occurrence, I see no problem with going all out: The planets in the system are destroyed. The star is destroyed. The wormholes leading to that system are destroyed. All ships in that system are destroyed. This also adds other strategic tradeoffs regarding the escort fleet as well as future plans for invading/defending from the enemy empire. As soon as the nova bomb strikes its target, the sun, the sun explodes, covering the screen with brilliant white light. From there, you are returned to whatever screen you normally see after a battle.
I think this could be a very interesting strategic addition to the game if properly implemented. Thoughts?
