What is the best tools to develop mobile base game

Question

game development

Answer 1

I agree with Lucien. Unity is a very well rounded engine, and does very well in terms of cross platform support. As well, it does a great job of supporting both 3D and 2D games. C# is a great programming language also, so I would recommend going with that. UnityScript/JavaScript is being removed from Unity and they'll no longer be supporting it, so I would recommend focusing around C# for it.
