but I don't think you really answered my question...
I was asking what do you think the negatives, if there are any, around using ideals, bonds and flaws in the same way you use aspects (extra questions, building the setting around the answer, etc.) to worldbuild.
Yes and I was hoping to get you to expound on why you believed that...
One of the core problems, IMHO, is that even if you expanded the Inspiration Bonds system, it would still be a mostly secondary to the core game. As such, the amount of effort that you need to put in to making Inspiration Bonds work as a more critical player-facing world-building mechanic may not be worth the gains.
You could definitely use Inspiration Bonds to world-build, and it may be worth looking into it for players to think more about their characters. However, this process in 5e is undoubtedly more detached from the core mechanics and character creation process than it is in Fate, where it is an explicit part of the Social Contract of its gameplay. Inspiration is not given much elucidation or support in 5e. It ties itself primarily to Background and so, in some regards, it is narrower in its scope and application. Furthermore, it's also an issue of how these player aspects in Fate empower
additional player-facing "world-building" in play, but I will get to that later.
EDIT: Backgrounds are only out of sight out of mind if the player and GM choose to ignore them... which they could also do by never compelling them in FATE...
My impression here is that the Inspiration Bond system is so haphazardly vestigial to 5E that it is often not a matter of whether "the player and GM choose to ignore them," but, rather, whether "the player and GM choose to include them." I think that this latter point is more often than not a better representation of how Inspiration-Bonds play out at most tables: a proportionately equal afterthought to playing the core game.
Yes and you could also do this by selecting the Dragonmarked feat for House Cannith and writing up backstory (or tie it into your ideals, flaws and bonds)... Given a GM and player who want this to be a part of the character and world equally in both systems...what, from a worldbuilding perspective, in FATE makes this "meatier" than other games where you say took the feat and tied it to one of your flaws, idelas or bonds?
You could agree upon nearly anything that you want for your character's backstory. This is equally true for both 5e D&D and Fate, so much that it borders on a tautology. Yet there are a few pretty big critical differences here between 5e and Fate.
IME, I would say that Fate's comparative "meat" in this regards, however, comes from the 1) mechanical prominence, 2) degree of empowerment, and 3) play consistency and frequency of these systems. But these three dimensions are intricately tied, so I can speak of them together with some contrast with D&D 5e, since that seems to be our comparison point.
As I said before, the Inspiration-Bond mechanic is more vestigial to character creation in 5e. In contrast, Aspects (e.g., High Concept, Trouble, etc.)
are character creation in Fate. Your aspects define who you are or, alternatively, how you define yourself. The core of your character concept are these aspects, particularly the High Concept and Trouble, which are primary pumps of your character concept's "heart" and the Fate point economy. The game book encourages you to build setting in your character concept as expressed in your aspects. From the Fate-SRD:
Lenny and Lily settled on the “guy and girl with sword” idea, and Ryan’s going with “guy without sword.” But those are just starting ideas. Now it’s time to turn them into proper high concepts.
Lenny latches onto the idea of tying his concept to an organization, and starts with “Disciple of…something.” He envisions a character who has trained in some mysterious martial art, and that involves rival schools and foes that want to learn those secrets. The group helps him come up with a suitably mysterious name: Disciple of the Ivory Shroud. (And now we’ve made a bit more setting: there’s an Ivory Shroud, mysterious martial arts, and all that implies.)
You cannot create a character in Fate without a High Concept and Trouble, but you could create characters in D&D 5e without Bonds. Arguably but uncontroversially, the primary focus in D&D is on Race/Class combination. What about Background in 5e? It's honestly a bit more secondary. It's primary perks are Two Bonus Skills > Two Bonus Language/Tool Proficiencies > Bonus Starting Goods. The Inspiration System is tacked onto Background. (
Why does my character flaw stem from being a Guild Artisan?) Thus it is ironically relegated to the background of the Background system.
In Fate, this is less about your "Background" and more about your "Foreground" of who you are playing. It's about establishing who you want to play and what you want to see in play. It is core to your character concept. It is your character pitch. You will be invoking aspects, and your aspects will be compelled. There is a consistent engagement in play with those aspects. This is more mechanical "meat" than Inspiration. When you use a Fate point (aka Fate's "inspiration" mechanic), then you will likely be invoking off one of those aspects for the bonus, re-roll, or the "other worldbuilding" thing that I alluded to earlier. That worldbuilding thing is "Declaring a Story Detail." A player can invoke one of their aspects - though with the GM's right to reject it - to declare the existence of a story point that works in the advantage of the player/character. Here is the example that Fate uses:
Zird the Arcane gets captured with his friends by some tribesfolk from the Sagroth Wilds. The three heroes are unceremoniously dumped before the chieftain, and Amanda describes the chieftain addressing them in a strange, guttural tongue.
Ryan looks at his sheet and says, "Hey, I have If I Haven’t Been There, I’ve Read About It on my sheet. Can I declare that I’ve studied this language at some point, so we can communicate?”
Amanda thinks that’s perfectly reasonable to assume. Ryan tosses over a fate point and describes Zird answering in the chieftain’s own speech, which turns all eyes in the village (including those of his friends) on him in a moment of surprise.
Ryan has Zird look at his friends and say, "Books. They’re good for you."
Similarly, we could turn to the point of our previous character, the Disgraced Ex-Bodyguard of Prince Alfric. The players may be trying to sneak into the manor of the prince. The players fail to find a suitable "conventional" entrance into the manor. The Player then turns to the GM with a Fate point and says, "So because I am the 'Disgraced Ex-Bodyguard of Prince Alfric,' I know that there is a secret tunnel that leads from the kitchen in the manor to the garden." That character's world-building aspect has just empowered the player to world-build some more amidst gameplay. It did not stop at character creation. This IMO "meatier" because the worldbuilding here is more substantial to the core player-facing mechanics. I seriously doubt that the Inspiration-Bond system would ever see play like this.
An Aside: Point #2 (i.e., Degree of Empowerment) also gets into the point that I raised earlier about level-gating character concept. Feats limit this concept in 5e, but that is not the case in Fate. Unfortunately we don't know what a Dragonmarked feat system would like in 5e, and it is questionable that it would have one. After all, how to implement Dragonmarks is one of the big debate points when people talk of porting Eberron to 5e. If you make it a feat system in 5e, then this means that only humans can start at 1st level in their Dragonmark. And due to the Ability Score Improvement, you are forcing players to decide between Character Functionality and Character Concept. Often, IME, the former wins even though the latter is more desired. So let's instead operate on the principle that the 5e Inspiration Bond system applied to 3.5 Eberron. If I were in 3e, then my character concept is limited by the Dragonmarked feats available for my level, such that I can only take Lesser Mark of Making (?). But my desired starting point for my character may be at a more "advanced" point in my character's life when they already have the Greater Mark of Making. I could start my character in Fate with that as an aspect; however, D&D says "no" because it ties these things into power level and an increasing degree of mechanical advantages. In terms of worldbuilding as an aspect of character creation, this means that there is more inherent worldbuilding potential out of the gate mechanically with a Fate character than with a D&D 5e character. This is not a value judgment on D&D 5e. It's simply about recognizing the limitations, strengths and weaknesses, and benefits of different systems.
