The demo is short and sweet but does enough to demonstrate that PlayStation 4 has the power to create a visually detailed experience while maintaining a coherent stereoscopic image at a sufficiently high frame-rate. It feels as if it has the quality to work as a full game, though beyond the confines of the demo you do have to wonder whether it would work as anything other than an on-rails experience.
It also serves to remind us that while Sony has - quite rightly - aimed for high frame-rates and fast response, we are still dealing with a 1080p image, which remains just as soft as it did on the prototype. The right trades have been made though. The lack of clarity doesn't detract from the quality of the overall experience, and obvious image quality artefacts - like edge-aliasing for example - are relatively slight. We spotted some minor jaggies on the shoulders of our captor, but that was it.
Secondly, the Heist demo emphasises the importance of PlayStation Move as an intuitive way to interact with the game world. While we didn't have access to the other three demos Sony has brought to GDC (we'll be looking at those later in the week), our prior experience of Morpheus demos using a standard Dual Shock 4 pad just isn't in the same league. What's really impressive about the London Heist demo is that interaction with the game world is intuitive - and obvious. There are no visual cues about where to find the gun, or how to load it - doing so is simply second nature. In the process, it feels fresh and exciting.
