I think a good example is Team Fortress 2 and Left 4 Dead. They belong to same genre and were built on the same engine. They look and have aged differently. TF2 still looks pretty while L4D is already showing its age. Despite this L4D is more demanding on hardware. Realistic games are much harder to pull off IMO. Another example is artistic Unreal games like Dishonoured and BioShock Infinite in comparison to stereotypical "brown and grey" shooters on the same engine.
That said I do appreciate photorealistic games more because it takes tons of effort and looks really cool. Sometimes it feels as if you are actually there. I last got that feeling with Last Light Redux and Alien Isolation.
I predict that the Wii U will sell a total of 18 million units in its lifetime.
The NX will be a 900p machine
