The choice of a framework depends on your preferred programming language and platform. For cross-platform development, Unity and Godot are two excellent options. Unity uses C# and is ideal for both 2D and 3D games, offering a vast selection of assets and multiplayer tools. Godot, with its open-source GDScript, is lightweight and easy for beginners to pick up. For web-based Ludo games, using JavaScript with frameworks like Phaser.js or Three.js is a good choice. If you want to go for mobile-first, you can also use Cocos2d, which is lightweight and works well on iOS and Android platforms. The choice ultimately depends on your target audience, game complexity, and familiarity with the tools.
