After you finished building your fourth iOS game with Unreal Engine, you have learned more about Unreal Engine. It was worth learning how to add custom inputs to your custom events, how to use the timeline node, how 2D colliders are optimized and why they are the best solution for 2D games, and finally a platformer on an iOS device should have virtual controllers that Unreal Engine makes possible using its unique and easy to use touch interface.

Now you have made four nice games, and it is time to move beyond the process of creating game logic and learning more about the other social and monetization features that Unreal Engine 4 provides.
