Depends

Should I use Unity?

Develop, deploy, and grow with Unity, the world's leading 3D game engine. Build for all major platforms from mobile, to PC and console as well as XR, acquire players, monetize your game, and power industrial applications. - unity.com

· 1 month ago

Buy Unity if you're shipping a serious 2D/3D game to mobile, PC, console, or XR — it's the industry default. Skip it for simple hobby projects or non-game apps where free engines like Godot do the job without licensing risk.
