Umm no? How does not actively pursuing kingship decrease my chances of eventually becoming king? While it doesn't advance my goals, it certainly doesn't hurt them either. Same with pretty much every other goal I listed.
Any time you spend not maintaining alliances, recruiting allies, proving your leadership, fighting off opposition forces, etc. results in alliances failing, missed opportunities, and defeats, which reduce your standing, and decrease your chances of becoming king.
What, did you think becoming king was just a matter of walking up to the throne and going "Yo, I'm king now, and you are all going to obey me"?
No, It's a lot of work.
Killing 3500 people a year is a HUGE amount of slaughtering for a kingdom. You're depopulating a large town every year. That is by no means slow.
For any reasonable size kingdom it'll take centuries to complete at that rate.
Anything that takes centuries is slow.
I see. "Do what I tell you to do or I'll beat you with the punishment stick" isn't railroading. It's instead, "realism".
Why do you assume there's a punishment stick?
If the players don't mind the dragon converting his populace to dragonborn, then the populace being dragonborn isn't a punishment.
If they do? Then they'll try and find time to do something about it.
Note, I do not believe that all goals are time based. However, that does not mean that none are. It's not binary.
But any goal that's time-based is, by your statements, a punishment stick.
Hrm, I can try to advance my own goal, which means I am going to get actively punished for advancing my own goals, or I can submit meekly to the DM's choo choo line and not get punished.
Yeah, that's a decision point.
You can try and fight the dragon now, or accept a few deaths in order to fight him once you are the greatest swordsman in the world, and thus more likely to win.
You can try and fight the dragon now, or accept a few deaths in order to fight him once you are the king, and thus have an army to march beside you and hold off his minions.
YES, that's a decision point
No, again, that is not the "only alternative". It's not binary - either all goals are time dependent or none of them are. That's ridiculous. There are all sorts of goals that are most certainly not time dependent. Most dungeon crawls for example aren't really all that time dependent.
Dungeon crawls are exactly what I was pointing at when saying "here's a dungeon here. It's not doing anything, no-one is being harmed, at all, but there might be some cool stuff down there"
Some plots can be time dependent. That's fine too. I loved the plot line in the Savage Tide AP where the pirates are going to attack your town in a few months and you have to rouse the defense of your homes by utilizing both the resources at hand and finding new resources on the Isle of Dread. Great time dependent plot.
So, if you don't defend your town now, you get hit by the Adventure Path punishment stick, of having your town destroyed?
How is that different from the "punishment stick" of a growing dragonborn threat?
But, it's also a railroad. If the players choose not to defend their home and instead pursue their own goals, the town will be destroyed and their lives will be more difficult.
You have a very idiosyncratic definition of railroad then I guess.
You define railroad as "time-dependent choice"
And then complain that there are no time-dependent choices that aren't railroads?
Yeah.
I mean, how would you react if the dragonborn presence was growing while your town was under threat? Is that TWO railroads that the GM clearly expects you to follow simultaneously? Or is it, as it seems to me, a difficult choice?
How is "Become the greatest swordsman" time-dependent? I'm curious - especially within the structure of a D&D campaign.
Simple. there are two ways to mean "become the greatest swordsmen":
1. Just becoming the greatest, no-one need know. Any time spent schmoozing, building alliances in order to become king, seeking out romantic relationships etc. slows you down. Other swordsman will come and go, and you may pass adventuring age, or be saddled down with responsibilities, without ever having become an epic level character.
This is less time-dependent, but actually still pretty time-dependent if you're playing in a game that tracks time.
2. Becoming KNOWN as the greatest swordsman. This requires that you spend time personally tracking down and fighting the most famous swordsman in the world. Any time spent not doing so will result in more famous swordsman arising, and the ones you have defeated falling from fame, such that you may never be unanimously agreed as greatest; and you may find that other things pull you away from said aim before you can achieve it.
