We've been talking internally about switching from Unity 3D to Unreal Engine (UE4). Here is my breakdown of the pros and cons of switching to UE4.

Cons

• Unity has larger userbase
• Possibly less optimized for mobile
• Possibly less optimized for 2D apps
• Years of development on Unity could take years to replace with Unreal

Pros

• Quality/ visual fidelity
• Possible performance improvements
• C++ is our developers native coding language
• More responsive product team
• More affordable
• Visual system for blueprint/shaders
