The actual racing is fine, apart from the usual complaints about GT games (the stupid licence tests and rolling starts, mainly) - like, I can see a justification for stuff like the International A and B licenses, arguably the A license, but don't make me do the B License when 90% of that is stuff that you've already made me do in actual races, and the remaining 10% of it (the stopping and starting in a straight line) is stuff that the game doesn't ever make you do again.

Most of my niggles with it are outside of the racing. In order of appearance (takes a deep breath)

• The hours needed to install the game. Doesn't seem fair to level that at GT7 specifically though, that's just modern consoles I guess.
• Forcing me to play at least one round of the shitty music rally minigame. My impression was that it was there to give the player something to do while the game is installing, but I left the PS4 installing the game by itself while I did a day of work, so to find that I still had to do it and couldn't just skip straight to the game... hnnnngh.
• The unskippable nine minute long intro sequence. Sure, it's skippable after the first watch, and can even be turned off, but you still need to sit through it the first time. NINE MINUTES.
• The "menu book" concept is utterly ridiculous, given that it basically just gives you missions, and later unlocks an actual Missions area that could have just been used for this.
• So much unnecessary dialogue with characters that I couldn't give a shit about. Forza Horizon 4 did this too, but at least that had the decency to have the audio/subtitles appear as "background noise" while you carried on interacting with the game, here you get interrupted by it.
• No way to turn off the automatic replay the end of a race. I just fucking played it, I don't want to watch it again.
• When completing a license test, there's no quick option to just go to the next test, you have to exit the "race mode", quit out of the auto-replay, then exit out of the menu it drops you in to. Three button presses with associated loading times that could be replaced with a single button.
• When you quit out of the auto-replay after a race, the next screen has the cursor pointing at the "Replay" option by default. I've just quit out of that, why would you assume I want to go back in? Default to Exit, or let me use circle to exit without moving the cursor there (it may actually do that last bit, I don't recall trying)
• Why does the right-stick move the cursor like a mouse? Does *anyone* use that means of moving the cursor over the D-pad style?
• If you buy a paint colour in the paint shop, there's no quick option to just apply that paint to your car. You have to go into the Livery Editor, create a new livery, manually apply the paint to each part of the car, then save the livery (and give it a fucking name!), and *THEN* apply it to the car - I'm not an automotive Picasso, I just want my Ferrari to be Rosso Corsa instead of silver.
• When buying a paint colour, you can see how the paint looks when applied to four (or five?) "sample cars", but not the actual car you're currently using - which would make sense if the car you're using has a complex livery applied, but if it's just the base colour still then that makes no sense at all.
• Tuning parts being winnable in the raffle thing, even though you (a) can't sell them, and (b) might not have the car that it applies to, and (c) might not have any interest in getting the car it applies to
• Cars not being sellable. They could even allow players to sell their cars in a used car market online (which I think Forza Horizon does?) - there's a Used Cars section, why not use the "always-online" features to do this?
• The always-online thing is bollocks, full stop. There can be very little justification for requiring an always-on connection for single-player play and progress. It's not like FH which brings players into the open world.

I think that's it, I've probably missed a couple of things
