It was also quite astonishing that Kaz himself runs in the real 24 Hrs of Nurburgring, he knows exactly what type of cars run in it and then when does he do for the game? Has us needing to run an LMP1 car or similar in the race to win it. Truly baffling.
How about LMP cars at the Indianapolis 500. What. If licensing or whatever stopped them from making it a Formula GT or Ferrari F10 race, it should have been left off the list entirely, instead of making a mockery of the 100 year old openwheel race.
I must say it still shocks me to this day of the 9 endurance races in GT5, only 1 was new to Gran Turismo, the Indy 500.
Obviously things are not quite right at PD for not only the above mentioned blunders to somehow sneak through the cracks, but also the other numerous head scratching design decisions that appear to display laziness or quite frankly a "dont care" attitude.
I dont mind classic endurance races like the Grand Valley 300 returning, as long as theres plenty of new endurance events to keep it feeling new and fresh. Around 20-25 would be fine I suppose.
In terms of replacing the 9 hours of Tsukuba, they need to first capitalize on the licenses they have. If NASCAR returns, add the Daytona 500. If they get V8 Supercars, add the Bathurst 1000km. With F1, perhaps a 78 lap Monaco race. FIA GT? Spa 24 hours. United Sports Car Racing or Daytona Prototypes? Daytona 24 hours. They had the 1000km Super GT race, but that was really the only endurance race that took advantage of a license.
Then they need to have enough variety in the endurance races with varying rules so each one is leans toward a certain segment of cars. For example, how about an endurance race that only allows cars made before 1970? Or an endurance race that doesnt allow tuning parts, or one that doesnt allow racecars, or one that only allows Italian cars? The non licensed endurance races should avoid becoming too specialized though. Making an endurance thats "Miatas only" really hurts its replay value, as you can't try it with multiple cars.
Also, the length of the races need to be shorter overall. In GT5, there were too many long endurance races, and not enough short ones. People may want to race a favor enduro of theirs over and over, and they're less likely to do that if its 4+ hours long.
In GT5, the estimated length of the enduros was, from shortest to longest: 2hrs, 2hrs, 3hrs, 4hrs, 4hrs, 5hrs, 9hrs, 24 hrs, 24 hrs. Only two 2 hour races is not enough. There should be more of those around that length. A rough number I would suggest is 7 or so 2 hour races, 7 3-4 hour races, and 7 6-24 hour races. Thats seems equal and fair enough
