how to make a game
Well the best way is to download unity engine or any other engine ( i use unity for my games) and then take some time to understand it then you can make games it just needs some practice and assets or you can make your own assets for 2d art use photoshop and for 3d use blender.
According to me, Unity is the best game engine for beginners, Godot is also more geared toward beginner developers. I had sad experience with CryEngine, but may be it's just me
