Unity vs Godot for a 2D Fighting Game: Why I Chose Unity for SAMT: All Stars
Cet article n'est disponible qu'en anglais pour le moment.
Engine debates tend to get more heated than the actual decision usually deserves. Here's the honest reasoning behind choosing Unity for SAMT: All Stars specifically.
The actual deciding factors, in order of weight
For a genre as timing-sensitive as fighting games, the engine matters less than how deliberately you build the fighting-game-specific systems (hitboxes, input buffering, frame data) on top of it — most modern engines are technically capable of the job.
- Prior experience and existing tooling familiarity — building on an engine I already knew well meant more time on the game's actual systems and less on relearning engine-specific workflows.
- Asset and plugin ecosystem — Unity's longer history means a deeper pool of existing tools and community solutions for genre-specific problems (hitbox visualization, input handling utilities), which reduced the amount built entirely from scratch.
- 2D tooling maturity — Unity's 2D-specific tools (sprite handling, 2D physics, animation) were mature enough for the project's needs without extra plugins.
Where Godot is a genuinely strong alternative
Godot has closed much of the gap in recent versions — its scene system is arguably more intuitive for 2D-first projects, it's fully open-source with no licensing terms to track, and its GDScript (or C#, if preferred) is approachable. For a team without prior Unity-specific experience, or one prioritizing open-source tooling from the start, Godot is a legitimate first choice, not just a fallback.
Comparison table
| Unity | Godot | |
|---|---|---|
| 2D tooling maturity | Strong, long-established | Strong, arguably more 2D-native by design |
| Licensing | Commercial, terms have changed over time — check current rules | Fully open-source (MIT), no licensing concerns |
| Ecosystem/plugin depth | Larger, longer history | Smaller but growing steadily |
| C# support | Native and mature | Supported, GDScript is the more native-feeling option |
| Learning curve if new to both | Moderate | Often considered slightly gentler for 2D-first projects |
What actually shaped the fighting game's feel (engine-independent)
Regardless of engine, the systems that make a fighting game feel responsive and fair are built on top of whatever engine you choose, not provided by it: precise hitbox/hurtbox handling, consistent frame data, and deliberate input buffering. Getting these right mattered far more to the final feel than the Unity-vs-Godot choice itself.
Choosing an engine for your own project and torn between Unity and Godot? The honest answer is that either can work well — the deciding factor is usually your team's existing familiarity and the specific tooling gaps you'd need to fill, not a universal "better" engine.
Questions fréquentes
Is Godot capable of handling a fighting game's precise timing needs?
Yes, in principle — Godot has matured significantly and precise frame-based logic is achievable in it. The choice came down to ecosystem and prior experience more than a hard technical limitation on Godot's side.
Is Unity's licensing a concern for indie fighting game developers?
It's worth checking current terms before committing, since licensing terms have changed over time and vary by revenue tier — this is a real, non-technical factor in an engine choice that's easy to overlook early on.
Does engine choice actually affect fighting game feel that much?
Less than framework-agnostic factors like input buffering design, hitbox/hurtbox precision, and netcode (if online play is planned) — the engine provides the tools, but the fighting-game-specific systems still need to be built deliberately regardless of engine.
