Final reply, since I won't be responding further on this.
I'll address your updated post point by point, because the "list of similarities" does not survive scrutiny once you separate ideas from expression.
First, the legal baseline. Copyright protects expression: source code, art assets, music, exact UI files. It does not protect ideas, mechanics, genres, or game systems. This is not my opinion, it's the foundation of copyright law (the idea/expression dichotomy). OpenFront cannot own "territory conquest on a map" any more than it can own "first-person shooting," especially since OpenFront is itself a fork of WarFront.io and openly inspired by Territorial.io.
Now your list. Every single item is a genre mechanic, not protected expression:
- Large top-down map territory conquest: the entire .io territory genre (Territorial.io, Generals.io, Risk). Not OpenFront's.
- Colored player regions expanding: same. This predates OpenFront by decades.
- Player names and numbers on territories: a standard RTS HUD convention.
- Match flow (pick start, expand, attack, compete): the definition of the genre, not an OpenFront invention.
- Leaderboard/stat panel: present in essentially every competitive multiplayer game.
- Full-map strategy presentation: a camera choice shared by all top-down strategy games.
None of these is copyrightable. A concern built entirely from unprotectable elements is not a copyright concern.
Second, and this is decisive: look at the actual visual expression, which IS what copyright protects. OpenFront uses flat colored "blob" regions over a satellite/political-style basemap with generic system fonts. Hegemon uses a hand-styled "Carte d'état-major" aesthetic: topographic contour lines, period cartographic textures, a locked custom art direction, and custom typography. The two games do not look alike in any element that copyright actually covers. Side-by-side, that is obvious, and your own comparison screenshots show it.
Third, the engine point you keep minimizing actually matters. Hegemon is built in C# on s&box (Source 2). OpenFront is TypeScript running in a browser. There is no shared codebase, no ported code, no shared asset pipeline. You have confirmed yourself that you never inspected my code, files, or assets, so there is no evidence of copying because there is none.
Fourth, the changelog. "Inspired by OpenFront" is an honest acknowledgment of creative influence. It is not a license credit and it is not an admission. AGPL-3.0 attribution obligations apply only to forks and derivative works that reuse the licensed code or assets. Hegemon reuses neither, so it is not a derivative work and the AGPL does not apply to it. Adding a voluntary inspiration line is transparency, not a confession, and using it as "proof" is backwards.
You have forwarded everything to the OpenFront developers. Good. I welcome it. If they have a genuine concern, they can contact me directly and I will respond with my project history and sources. But two games sharing a genre is not infringement, and you have now admitted you have no proof of anything beyond visual genre resemblance.
This is my last message on the subject. I've said everything that needs saying, and I'm going back to building my game.
