We got laser weapons, some of us will have Armageddon bombardment and our ships are able to move faster then light.
I'm reasoanbly sure even our Corvettes could devaste any kind of 'modern atomic age' military installation. Or at the very least fry ICBMs as they start.
Some of these Atomic Age civilizations are just years away from having space flight themselves. Your ships are not capable of faster than light travel within the gravity well. And your corvette have never been able to "fry" the ballistic missiles launched directly at them, what makes you think they'd be able to stop a multitude of ballistic missiles launched away from them on the other side of a planet?
I understand the realism versus gameplay argument. But I'm not sure your position is realistic or good gameplay.
This is a fairly specific example that is only applicable to the very first few years of the game. After that, even a modest invasion force should be enough to eat any pre-Space Age civilization for breakfast.
Then after that I agree with you, before that I don't.
It also requires that literally no forethought has been put into the invasion: I assume that your general (or whoever is leading your invasion) is invading with knowledge of the enemy's capabilities and (roughly) what he/she should target. You do get a warning if an invasion is likely to fail, after all, so I don't think any invasion in the game is totally blind.
You're a big fan of the false dichotomy aren't you?
The choice isn't between "no forethought" and "can disable an uncounted number of nuclear arsenals stretched over an indeterminate number of industrialized nations."
And the choice isn't between "I have found every hidden installation on every nuclear power capable of causing mass destruction" and "we're going in completely blind boys!"
There's a middle ground, the middle ground that I suspect you are (roughly) aware exists and would acknowledge if you weren't arguing from a position of hysterical extremes. That middle ground is also impossible to accurately represent effectively in this game. Which is why the original poster suggests that there be a critical fail chance that leads to the kind of destruction that we presumably reasonable humans were prepared to cause one another rather than lose the cold war. And why I agree with it, and think that critical fail chance should be modified both by the length of the war by a people's tendency towards xenophobia, militarism and egalitarianism.
