It's been a while since we published a Godot vs Unity comparison, and both have had updates in the intervening period. Unity remains the most-used game engine, but Godot is becoming increasingly popular among indie developers, with Mega Crit making the transition from Unity for Slay the Spire 2.
Godot is free and open source (also see our guide to the best game development software), but could it also be the better engine for many developers? It's rare to see a direct like-for-like comparison of two both engines since that would require making the same game twice, but that's exactly what one developer started to do, beginning his game in both Unity and Godot to see how they compared. His conclusion might surprise you.
