I like it and I hate it. Obviously as far as graphics goes, this gets a 10 out of 10, but I'm reviewing this based off of gameplay, and oh boy...
The driving is okay, not always enjoyable, a lot of the cars just have atrocious handling that wouldn't be expected in the real life counterpart. For example, I've had the opportunity to take a BMW M4 around a track irl and it handled like a race car, but the one in Gran Turismo? Just terrible. Again this is an example of just one car, it does thus with many. However sometimes the cars are nice to drive, it is a simulator, and not a simcade or arcade racer, so if you're new to the franchise it will take some getting used to, but you'll learn how they handle.
Some big cons:
Some challenges can me near impossible to complete, especially the drifting ones.
Difficulty between circuit experiences are huge, some are easy, some are ridiculously difficult.
Money. In game money earned in GT7 is close to nothing. This then diverts players to micro transactions. "But bro why would people buy in game money if they could just earn it over time?", because the cars have insane price tags, that's why. A high income race is an average of 150k credits for a 10-20 min race. Some cars cost up to 20Mil credits, so micro transactions are a necessity if you're desperate to buy the car. Oh, did I mention that some of those lovely cars have a time window and eventually dissappear from the store? Yeah...
The menu books. The Cafe is a new addition to the franchise, where you can aquire free cars for completing races, sounds cool right? It is! BUT you need to grind the menu books in order to unlock general facilities within the game, and this can take hours. Think of it as the entire game being one long tutorial.
Okay some pros:
Again, some cars handle like a dream, making it a really enjoyable experience
Customisation of the cars exterior is something we've been missing for a while.
Cars can be upgraded with equipment like new brakes, nitrous, air filters and the list goes on
The selection of cars isn't fantastic, but it is more than the previous game, so I decided to put this as a pro
Overall I'm giving the game a 3/5. It can be awesome, it can be rage inducing. Would I recommend it to peeps? Yes, I would. If you're new to sim racing then it will take a while to get used to. Hope this helps anyone that's thinking of getting it.
