An external front-office / GM tool for a CFB27 dynasty. It runs alongside the game as its own Windows app and takes over recruiting, the transfer portal, coaching moves, and NIL, while CFB27 keeps doing what it does best: playing and simulating games.
The app opens your real dynasty save, reads it directly, and writes decisions back into it when you commit them. There is no separate universe to keep in sync, and no re-entering your roster or your class by hand.
This is barely alpha. Do not start a real dynasty in this tool yet.
I would normally keep a build in this state private. I am sharing it because I have spent a long stretch building it with nobody looking at it, and I do not yet have enough people involved to get the feedback I need before committing to serious tuning, refinement, and testing. That feedback is the entire reason this release exists.
What that means concretely:
- Systems are brittle, and the full season can easily break while I am making changes this rapidly. Do not expect to play a real dynasty. It may very well break along the way.
- Numbers are untuned. NIL prices, commit odds, portal behavior, and generation targets are all first-pass values, not balanced ones.
- Data can break between versions. The tool keeps its own per-dynasty database alongside your save, and its shape is still changing. Migrations exist, but at this stage I will discard that data rather than carry a bad structure forward, which has already happened once.
- Treat every dynasty you open with it as disposable. Back up your save yourself before you point the app at it.
The right way to use version 0.098 is to look around, break things, and tell me what is wrong. Not to invest 15 seasons in it.
I write the vision docs, the requirements, and the test cases myself, then lean heavily on AI coding to build from them. There is no way I could write all of this code on my own.

CFB27's on-field game is deep but overall the game is designed to allow using multiple teams, having multiple users, and an experience that allows you to just jump around without it breaking. I think a single player focused experience that sacrifices some of that flexibility for depth could be very rewarding.
Yes this is a single team project only but is intended to allow you to take new jobs within it. Single team focus may change in the future.
Dynasty Engine is not a companion dashboard you glance at. It is meant to be opened at the start of every single week of your dynasty, and it replaces a large amount of what you would otherwise be doing inside CFB27.
The loop, in order, every week:
- Open Dynasty Engine and load your save. Pulse, the landing screen, is the week brief: what needs a decision from you this week, plus a wire of everything that moved since last time.
- Do the front-office work here. Scouting beats, sorting the board, cutting NIL offers, making and grading promises, working the portal during its window, retention, coaching moves. None of it happens in the game anymore.
- Commit, then close the app. Every decision that touches the save is explicit and previewable, and the app checkpoints both halves (your save and its own database) before writing. The app never writes to your save on its own while you are away.
- Go back to CFB27, play or sim the week, and save in-game.
- Come back to Dynasty Engine for the next week.
Both directions of that loop matter. The app is the only place recruiting happens, because the mod zeroes the game's recruiting and scouting hours. And the game is the only place football happens, because Dynasty Engine does not simulate games at all. If you skip weeks in the tool, offers expire, visit windows close, and recruits commit elsewhere without you having had a say.
What the tool now owns instead of the game: all recruiting and scouting, all scholarship offers, all NIL (in real dollars, the game's own NIL numbers are zeroed on purpose), who enters the transfer portal and where they land, coaching-carousel moves, and player development between seasons. What the game still owns: everything on the field, plus the roster and results the tool reads back out of your save.
Dynasty Engine is two halves, and you need both.
The mod (Dynasty-Engine-v0.098.fbmod) is small, and everything it does is
about getting the game's own systems out of the way. It zeroes the weekly hours
coaches spend on in-game recruiting and scouting, so the game's click-to-recruit
loop has nothing left to spend and recruiting only happens through the app. It
retunes recruit generation down to the archetype: the game's own generator still
produces every prospect, but the mod reshapes the star ratings it hands out so
position value looks like real recruiting, with more realistic 4-star and 5-star
counts and no 1-star filler. It also renames and repurposes three coach talent
trees so what you are buying reads correctly, and suppresses in-game player XP,
because player progression is the app's job now and it should not be decided in
two places at once. Games and on-field simulation are untouched vanilla CFB27.
The app does everything else: it parses your save, layers a persistent per-dynasty memory on top for what the save does not track, turns off player-initiated transfers, clears in-game NIL so no stray number implies the game is handling it, and writes every decision back explicitly, previewable first and checkpointed automatically.
Prospects and the recruiting board, a real scouting network, commitment decisions that weigh six factors per recruit, a self-correcting CPU league, a promise ledger tied to your coach's credibility, a fully simulated transfer portal, a real-dollar NIL budget, the coaching carousel and career legacy, league-wide staff report cards, an annual player-development pass anchored to the real base roster, and the Vault's paired checkpoints.
Each of those is marked in Features with where it actually stands. If something is not marked, ask.
- You see what a GM would actually know. Recruits are graded in bands and qualitative reads, never a raw hidden number pretending to be certainty. Rostered and portal players, who you would genuinely know the truth about, show real numbers.
- Real dollars, not an invented currency. NIL is priced in actual dollars against a real budget, because program wealth is a real-world fact the game itself does not model.
- Consequences are real. Declined offers, broken promises, and lost recruiting battles stay lost. The Vault protects against bugs and mistakes, not against the outcomes of your own decisions.
- Your save is never at risk from the tool. Every write is backed up first, previewable before it happens, and reversible after.
- The tool has memory the game does not. Player origin, coach career history, program ledgers: all things a real front office would track and the base game simply forgets.
A guided tour of the app, recorded against a real save.
It is the best way to see what the tool actually is before you install anything. Screens has still screenshots of most screens too, though they are older than the video.
Use the buttons in the app. The left sidebar has a Community section with Ask Question, Report Bug, and Request Feature. Report Bug is the important one: it bundles diagnostics (and optionally your save and dynasty database) into a folder, then opens the issue form so you can attach them. A bug report with that bundle is worth several without it.

This is the public side of the project: downloads, docs, issues, and discussions. All the documentation lives as markdown in docs/, versioned with the release it describes, so you can always read the docs as they were for the build you are running. The app's source lives in a separate private repo. This one exists so anyone can get the tool and find answers without needing access to the source.
