I just hope they fill out the lower categories. Having all the GTE and most of the GT3 cars is great, GT4 and TC feel lacking in PC2.
Also, more tacks from Asia, Australia/New Zealand and the Americas would be nice.
I can definitely agree on this. There's a lot of recent cars that can definitely help in boosting TCR and GT4. Some of which even come from brands with a lot of cars already such as Audi in TCR and Mercedes and Ford for GT4. TCR highlights a few manufacturers that have been yet to be as explored as other games like Honda with cars in Super GT and TCR as well as classics like F1 and Super Touring.
I'd say the same for other classes in game like LMP2 and the lower reaches of Open Wheel racing. (Formula 3) I'd much prefer them to add cars like the current F4 cars and F3 cars which could be the Tatuus T-318 used in FR Eurocup and W Series or the old Dallara F318.
Tracks around the world I can also agree on. There are also some big tracks in Europe that aren't in the game like Paul Ricard and Zandvoort. Misano has a few series as well so does the Hungaroring.
Elsewhere in the world is a definite with big, well-known tracks in Asia missing like Sepang, Shanghai, Bahrain. I'm happy with Japan but would love to see that further expanded with places like Motegi.
South America is completely untouched though there's a chance that the Automoblista link could help with this.
Ovals in America are a big thing with only 3 ovals with 2 of them being Superspeedways and no short tracks like Iowa or Gateway. As well as Iowa and Gateway, I'd recommend Pocono, Bristol, Charlotte, Dover, Homestead-Miami and Kansas.
Not to ignore the American Road Courses like Mid Ohio, Sebring and Lime Rock Park to mention a few.
