Answering to the main thread...
I like racing games and I usually dont enjoy sticking for the same sim/game by too long. For more than a year or two to be more precise. Also, I bought a wheel (T150) and I need sims and games to justify the expense. So, anything "so-so" or "more or less" is welcomed, making me vote yes.
GT Sport is far from being amazing and far from being very great. It is far from being a quantum leap from GT6.
However, we do have some shy, timid progress between GT6 and GTS: Graphical improvements, menu improvements (looking quite nice), good replay, better car selection (at least in my own opinion), better car grouping (N300, N200, Gr. 3...BoP is better than PP), sound improvements, online system improvements, and maybe a thing or two I forgot to mention.
The small track list is a bit disappointing - even if they were all real tracks. Some say about the 150 car list. I would like to remember that GT never really had 1000 cars in any single game. Somebody in GTP a long time ago counted that GT6 had about 450 different cars - 750 cars were just duppies. You know that 10 different models of Miatas first generation? For real, GT6 had about 450 different cars, with 1200 different models. GT5 had about 250 cars. So, 150 cars is not small as it appears to be - its 1/3 compared against GT6, not 1/9!
I expected more from climate and time change, and the physics improvements were minimum. Still no tire pressure option, still fictional units ("levels") for dampers, roll bars, differential and aero.
I think, in the end, for every positive I find a negative. Their problem is: PCars 2. I think and expect that SMS will do a much better job, even if I do not have any evidence for saying so. GTS looks like it is ages ago from the other games, they still have plenty of catch to be done (in physics for example). I imagine that GTS would be a good competitor against PCars 1 back in 2015. Or a very good alternative and the very first sim in PS4 back in 2014. Back there this game would be quite great, imagine this beta in 2014 or 2013. People would be more excited if the release and beta would be back in these years, and this is why I say: They are ages behind, they have 2-4 years of catch to be more precise (except in graphics and replays, they are 1-2 years on the front).
