Thanks for the thoughts, guys -- while I understand some prefer to have them always be in the game, I'm simply not going to be going that route. I've been down that road too many times before, and it's simply untenable. Here's the core key fact:
The golems and the spirecraft are
not a core part of the game. As in, you have to buy an expansion to get either one of them.
That means that to have it balanced with the golems/spirecraft in the core game in a balanced fashion means one of the following:
A. They have to be some form of self-balancing lame, as in the past, or
B. There has to be some sort of analogue powerful ships in the base game without any expansions, which devalues them, or
C. The expansions have to ramp up the difficulty simply by being enabled, in order to account for the golems' presence.
Suffice it to say, I was one of the players who did not use golems in regular play, and the few times I did even recently were kind of disappointing (an armored golem died
waaay too fast, etc). I've been chasing this for almost a year now, and I've simply had enough with that.
The minor faction idea isn't just the "simplest idea" for how to solve the problem, I'm pretty convinced it's the
only solution. Introducing various penalties and negatives and such are extremely hard to balance, and they tend to just make players not use them at all.
And for those complaining about higher difficulties: you're not losing anything here, you're gaining. Read my post again, I talked about two minor factions for each. One that makes the scenario harder, the other which just gives you beefed-up golems without that.
At any rate, I'm not really considering alternate suggestions for ways to make them implicitly balanced with themselves, as I've just been chasing that far too long and I'm convinced there's not a good way to do it. We've had hundreds of people making suggestions, and I've tried half a dozen or a dozen broadly different approaches, and nothing satisfactory has come of that in a year's time. That's when it's time to punt.
