The amount of OP Novalith threads is becoming disheartening.
It's not the Novalith that's actually OP. After so long with the novalith for what 4 years? It's only spammable and what people call "OP" once TEC loyalists are able to just rush it out with just 6 military labs.
It is the flawed AI that can't seem to be do anything else.
The AI with TEC loyalists will just rush out the novalith cannon probably because there is nothing to research behind it.
If you are gonna "nerf" the Novalith. Don't put this 2 superweapon limit unless you want to nerf the TEC loyalists to the ground. Instead just put a few missle researches behind it. Not all of them but at least some so it isn't as rushable and spammable. That's all the Novalith needs to make it "less OP". It's just only too spamable if anything when the AI on harder difficulties have money cheats. A player wouldn't be able to rush this many but it's only the AI issue.
Also it's a superweapon for a reason. Heck it isn't even the best superweapon. The Vasari have the best superweapon since they can just skip all your defenses and just jump in with a large fleet on your capital if they wanted.
