Good fit if
- You want no royalty or revenue terms ever (Godot Engine is the pick)
- You are targeting mobile and want a large ecosystem (Unity is the pick)
- You need top-end 3D graphics (Unreal Engine is the pick)
- You code in Rust (Bevy is the pick)
- You write Lua and want a small 2D framework (LÖVE is the pick)
Not ideal if
- You need paid-tier features, uptime guarantees or support that these free plans leave out
The question with a free game engine is not whether it is free, but what happens to that price when your game earns money. Godot, Bevy, LOVE, O3DE and Stride are open source under MIT, Apache or zlib-style licenses, with no royalties and no revenue conditions. Defold is free to use with no royalties, though its license bars you from selling the engine or editor. Unity Personal is free while revenue and funding stay under $200,000, with Pro at $210 a month beyond that. Unreal Engine is free to download and charges a 5% royalty on lifetime gross revenue above $1 million per product, under Epic's license terms. Beyond licensing, the engines differ by approach. Godot and Unity are editors with scene tools; Unreal is the heavy choice for high-end 3D; Bevy is code-first in Rust; LOVE is a small Lua framework for 2D; Defold targets lightweight 2D and mobile; O3DE and Stride are open 3D engines with smaller communities. Pick by the language you want to write and the kind of game you want to ship. Moving a project between engines means starting over, so decide before your first month of work, not after.
