After Mark Rein made his comments that UE4 will have to be scaled down to run on Wii U I decided to do my own research to analyze exactly what the PS4 version looks like. It appears the engine is also being scaled down to run on PS4 since there is a noticable difference in the effects and how much stuff they can put in the environment in real time. Obviously the Wii U version will not look better than the PS4 version but the question comes to mind that if the PS4 cant even run the engine to its full potential and Mark Rein did confirm that UE4 will be scalable to even Tablets and Smart Phones, Its pretty obvious UE4 should be able to run on Wii U with no problem. The only problem appears to be execs and developers (man power to work on porting the engine) interest in other systems since they believe it will be more profitable to make the kind of 3rd party games the engine is famous for (First Person Shooters). This makes sense since he made the statement that if anyone wants to port the engine to Wii U they can but they are not focused on it.
