Criticism is of little value without context and perspective. In much of the commentary, both fans and professionals, we have seen issues in an early build projected onto the final product. Eurogamer have essentially reviewed the preview build, there was precious little insight into the development process, or what can be expected in future builds and the final product.
Its little wonder few developers show early gameplay footage, let alone a build suitable for a stable online tournament. The daily build updates demonstrate how the performance and look of a game can change. The trailer image of the 2D Nurburgring tree line was spammed hundreds, if not thousands, of times, yet on the show floor the latest build had addressed that issue.
The same can be said about many aspects of GT Sport, tyre marks, reverb in tunnels, particle effects. All essential to the polish of a final build......but of little relevance to an online tournament (vs stability).
I'm absolutely sure GT Sport will have areas where it will disappoint, and maybe some of those will be old bugbears, making you wonder why they weren't addressed. But you have to give PD the time and space to deliver their final product, only then can we see if their decisions regarding dynamic weather etc. are worth. We'll get major updates/trailers along the way at E3, TGS & Paris, in fact GT Sport will be a great example to demonstrate how a title comes together in its final phases of development.
