I like some things about GT Sport, the physics needed a little more work and the penalty system always sucked but right now it's almost more fun to play than GT7.
In some ways, GT Sport is a lot more fun to play than 7. Not more realistic, but it feels grand to be in command of a racing machine and doing pretty much what you want with it.
So listen. We're all / most of us getting used to GT7's physics. But there is this matter that the cars in some aspects just don't feel or behave right. Some of us use real world racing experience with the same cars, some of us - Scaff - are involved with the technical side of the autoverse, and they're trying to get into the weeds to explain that something is definitely off with some aspects, mostly that elusive bit of code handling the edge of grip, but a few other culprits are likely involved.
And many of us are fairly well steeped in racing game experience. Many if not most of the non-race cars, and a bunch of them, need some help to allow us to race the darn things. Either assists, tuning - which many stock tunes just aren't right - or both. In video games and real life, it's usually fairly intuitive and self-instructive to get behind a wheel, push a car, and learn its personality. GT7 cars are just frooky enough where it counts, pushing the limit, that it makes racing stock unassisted cars kind of a pain because they will bite you without a split second's warning. And often leave you without a clue why.
I love this crazy thing, most of us seem to at least like it, but the "grumpy" side has one big point. The cars need the physics finessed some, and need to communicate these physics better, because it's eluding most of us on the Planet. I expect some action on that stuff very soon, maybe April, and then hopefully we can all have a pizza party in here.
