I was getting waves of 24,000 units on tech level I
Was this with golems, spirecraft, fallen spire, and/or champions on? And were you taking advantage of all of those that were on, or were some on just to keep the door open but you weren't using them (yet)? FS contributes corresponding to city structures so it won't nail you just for having it on, but the golems and spirecraft cause the increase in SD response even if you don't have any.
Anyway, what would have been a reasonable wave size, given the circumstances?
I spawned well over 700 artillery golems
Planet-cracker indeed.
I still lost because the GCS has infinite range and smacks your home command station through your force fields.
It does have infinite range but it's not supposed to be immune to forcefields (nor do I see that flag in the code). A while ago it was possible to hit something through a stack of ffs with a dense enough uber-salvo that the object lost the one currently tanking for it and didn't get to check for more ffs before the rest of the salvo came in, but I thought that was fixed a while ago.
Anyway, yea, you generally need to stop these before they make it to your HW. If you have no superweapons on then the GSCs themselves are really nasty but the other stuff coming in should be more manageable, and if you have any superweapons on then you should probably be able to kill a GSC in an ambush or three, depending on what exactly you have (an FS fleet will maul one horribly via wormhole ambush, a Spirecraft Penetrators/Rams can probably do similarly, and BB champ(s) can harry it with several suicide runs and do a lot of damage with the right modules).
The point was for it to be both challenging and possible (in favorable conditions) both without superweapons and with them, though the "everything on" case is supposed to be pretty nasty because then you've got all those toys to kill it with.
And I tried to see if going through all that effort actually paid off, but from what I can tell, it's only turning off strategic reserves at first which is the biggest help.
After the thirty minutes all waves, counter-waves, raid-engine-waves, CPAs, reinforcements, additions to strategic reserves, additions to special forces, exos (of any kind), etc... they all stop, permanently. At that point, any AI ship you kill stays dead and is not replaced (well, aside from regenerator units, but you get the idea). How long you have to take advantage of that depends on the map and HW placement, of course.
I found completing the showdown to be anti-climactic in the sense of, no journal entry and no fanfare for surviving that multipronged onslaught. And then comes the GCS, and it's all over anyways.
Well, the GCSs
are the climax of the showdown. You kill them, you win. You don't kill them, you lose.
I could add journals for charging-started, charging-finished, and GCSs-destroyed, but in the past the journals have had a pretty minor impact on player enjoyment (from what I can tell) compared to the time it takes to write and incorporate them, so I've been trying to focus that time on coding the new stuff and fixing bugs that were annoying people instead.
If the GCS is intended to be an instant win if it lands on your home command station, that should probably be in the journal entry as a clue.
That's a good point. It shouldn't be an instant win, depending on how many ffs you've got on the station, but a GCS being on your HW would be a "this game is going to be over one way or the other in about 10 seconds tops" situation.
This feels too difficult for the reward (you'd be better off attacking a command station).
Generally speaking if you don't have the force to take down the HWs you won't have the force to win by SD, no. Otherwise the normal victory method would become kind of rare, which isn't what I'm wanting. This is for when you think you can take the AI, and want it to bring-it-on. (edit: it's probably also significantly faster than playing through the rest normally, and lets you avoid any brutal-core-guard-post knots, etc)
The AI may perhaps be a little too enthusiastic about this, currently
