Important Notes:

-Tuning cars to get past certain events was not factored in because... it would take a criminal amount of time and effort to do so. But that still changes nothing, because it would only make GT7's grind even worse as the tuning is generally more expensive than in the other games and more events require cars being tuned as well.

-The total race count excludes every single event that is not listed as a race. For example, the driving missions in Gran Turismo 4 that involve 3 laps races to overtake the AI, did not count for this, likewise, the Gran Turismo 7 race missions (24 minutes of Le Mans and all of the "The Human Comedy" missions for example) were not included.

-I used race distance as a measure stick for the lenght of the campaign because time depends on the players skill level. For the races that don't have a set distance (laps), like the Timed Endurance Races (24hr Le Mans for example), the amount of laps used to calculate the "race distance" for that particular race, was the laps needed to beat the fastest AI. For example in Gran Turismo 5, the fastest AI in the 24 Hr Le Mans Race can do 387 laps, so 387 was used to calculate the "race distance", in this case it's 387 (laps) x the track lenght, which in this particular case was the La Sarthe 2009 (13.662 m) which gives us a total race distance of 5.287 km.
This same "race distance during campaign" does not include any of the distance done in driving missions, licenses, or any event that is not listed as an actual race. Though, I can arrange in the future to add these, IF they at least include a full lap around a track. I won't be counting any distance that is only measured across a single track section like the licenses tests and some of the missions for example.

-About 60 million credits of the total earnings in the GT7 campaign were added via updates in Gran Turismo 7 (after a huge outrage from the playerbase).
-PD slashed down the credit earnings in the very first update, to the point where the maximum credit grind method was less than 1 million per hour (they reverted on this decision as well for the same reason above). This was in Updated 1.07.
-The tendency is for the grind to get worse with GT7 given the constant price increase of the Legendary Cars and the addition of new cars that add to the cost, as the other games are finished.

-Gran Turismo 5 Seasonal events total earnings:
Which surpasses the credits needed to grind for the remaining cars, plus there's also a lot of expensive prize cars from those seasonals that also help a lot, some of which are 10-20 million credit cars. So Gran Turismo 5, across its 4 years of support, technically wouldn't need any grinding for cars and even XP. This however assumes the player would play the game during those 4 years, which is not realistic for the majority of people, so I didn't take the seasonals into account as a whole, but I did take it's best grinding method which drastically reduced the time needed for such.

-Gran Turismo 4 and 5 can have the grind eased up because of B-Spec mode.

-*Gran Turismo 3 is a bit more unique in the time and ways it takes to grind cars. There are 29 missable cars that have to be won from certain championships or endurance races. It's possible to win them as we progress through the campaign, but there are a few of them that are required to repeat an event to win them. As those events are repeated, we gain enough credits to buy the remaining cars, with plenty to spare, as we also get quite a few duplicates that can be sold for a considerable amount.
A minimum estimate for the time it will take to grind these cars will be updated in the future.

-*Gran Turismo 2, much like Gran Turismo 3, also has a few missable cars where we have to repeat certain endurances or championships to win them, so the overall time to grind is considerably more. Much like GT3, a minimum estimate time to grind those cars will be updated.
-*Gran Turismo 2 total race distance during campaign is not completely accurate because some events from the game (manufacturer events) have random generated tracks instead of specific ones to complete them. So the distance can be variable. I decided to go with the smalest track for a minimum distance required to do the campaign.

-*Gran Turismo 1, much like Gran Turismo 2 and 3, also has a few missable cars where we have to repeat certain endurances of championships to win them. The events however are much less repeatable because instead of a potential 4 cars we can win in an event like GT2 and GT3, in GT1 we only have 2 (50% chance each). A minimum estimate time to grind those cars will be updated.





To those people that think that it's tedius to grind in GT7, and have the feeling that it takes forever to grind to get anything in this game... That's because it actually is.
A roughly estimate on GT3: European championship, 4 races 5 minutes each race including reloading time, approx. 350k x 2 races each hour including loading times gives approx. 700k per hour.
