No Free Game Engine Meets All: No-Code + 2D/3D + Flash + DVD Standalone

No existing free engine satisfies every constraint:

No programming: True no-code 3D is near-impossible; logic *is* programming (visual or text).
Flash target: Flash Player died Dec 2020. Browsers block it. Export to HTML5/WebGL instead.
DVD standalone executable: DVDs are obsolete media. Modern engines export to .exe (Win), .app (Mac), .apk (Android), .html (Web). Burning an .exe to DVD works, but users must copy to HDD to run (autorun.inf disabled since Win7).

Closest Free Options (Compromises Required)

Engine	No-Code?	2D/3D	Export	Notes
GDevelop	✅ Event-based (no code)	2D only	HTML5, Android, Windows (.exe)	Best for pure no-code 2D. Free, open-source.
Construct 3	✅ Event sheets	2D only	HTML5, Android, Windows (via wrapper)	Subscription for full features. Browser-based editor.
Godot 4	⚠️ VisualScript removed; GDScript (Python-like) required	2D & 3D	All desktop, mobile, web	Most powerful free engine. Learn GDScript (easy).
Unity	⚠️ Visual Scripting (Bolt) exists but limited	2D & 3D	All platforms + console (Pro)	Personal free < $200k revenue. Steep learning curve.

Recommendation

Start with **GDevelop** (2D) or **Godot** (2D/3D, learn GDScript). Export to Windows .exe → burn to DVD if you must. Users will copy to desktop to play. Accept that **Flash is dead** and **no-code 3D doesn't exist**.
