When Unity Is NOT the Right Engine
We build games in Unity. It's where our expertise lies, and for most projects, it's an excellent choice. But intellectual honesty matters more than selling our services. Here's when you should consider alternatives.
Unity's Strengths (Quick Context)
Unity excels at: mobile games, VR/AR, 2D games, indie 3D games, rapid prototyping, and projects where C# expertise is available. It's flexible, has a massive asset ecosystem, and targets nearly every platform.
Now let's talk about when that isn't enough.
Unreal Engine's rendering is ahead of Unity's, especially for realistic environments and characters. While HDRP closes the gap, Unreal's Lumen, Nanite, and material system produce better results faster.
If your game's primary selling point is visual fidelity and you're targeting PC/console (not mobile), Unreal will get you there with less custom work.
Unreal has World Partition, Nanite, and virtual texturing designed for large open worlds. Unity can do large worlds, but it requires significant custom work for streaming, LOD, and optimization.
Projects like open-world RPGs or survival games with huge maps are easier to execute in Unreal.
Games like God of War, Spider-Man, or Uncharted are predominantly Unreal territory. The animation systems, traversal mechanics, and cinematic tooling are more mature in Unreal.
Unity can do it (Ori, Hollow Knight for 2D; some 3D examples exist), but you'll build more custom systems. If your team has Unity expertise, it might still be the right choice. If starting fresh, consider Unreal.
For straightforward 2D games - platformers, puzzle games, simple action games - Godot is lighter weight, truly free, and increasingly capable. Unity's 2D is excellent, but if you're very budget-conscious and the scope is small, Godot is worth evaluating.
Unity's per-seat licensing (if you exceed revenue thresholds) can matter for small teams with successful games.
Battle royales and MMO-scale games push networking to extremes. While Unity can handle it (Escape from Tarkov, for example), these projects often use significant custom networking solutions or server-side simulation.
Unreal's replication system is more battle-tested at scale. If you're building a 100-player shooter, Unreal's Lyra project and existing battle royale examples provide a stronger starting point.
When Unity IS the Right Choice
For most indie shooters and action games, Unity is excellent. Our projects (MATH FPS, ShadowStrike, TOGETHER: OR WE DIE) all use Unity because the scope, team expertise, and platform targets align well with Unity's strengths.
- Mobile games - Unity's mobile optimization and platform support is superior
- VR/AR - Better cross-headset support, more VR content examples
- 2D games - Excellent 2D pipeline, huge asset ecosystem
- Indie 3D games - Faster iteration, lower asset requirements than Unreal
- Teams with C# expertise - Don't underestimate the value of working in a language you know
- Prototyping - Faster to test ideas and iterate
- Projects under $500K budget - Unity's tooling gets more done with smaller teams
The Team Factor
Engine choice should factor in your team. A Unity expert building in Unreal will be slower and make more mistakes than building in Unity. The "better" engine means nothing if your team can't use it effectively.
If you're hiring a studio (like us), you're also hiring their expertise. We do Unity because we're good at it, not because it's always theoretically optimal. A team that knows Unity deeply will deliver better results than a team learning Unreal.
Our Recommendation
If you're reading this, you're probably considering Unity. For most indie FPS, action, mobile, or VR projects, it's a great choice. If your vision specifically requires photorealistic AAA visuals or massive open worlds, have an honest conversation about whether Unity can achieve it or whether Unreal makes more sense - even if that means finding a different studio.
We'd rather help you make the right engine decision than sell you Unity development that doesn't serve your project.
