With Turn 10 they aren't Biased against the whole Japanese dominant car culture. Whether American, European or Japanese, T10 are impartial to how fair they are with their broad list of models across the decades past. Not focusing on purely American brands. This is something PD need to do to change their status quo.
Lets see when it comes to Ford, there are cars like the Escort RS Cosworth and Sierra Sapphire Cosworth, Ford transit van, Ford Fiesta XR2, R200 Evolution. This is how selectable and varied T10 are. They pick iconic cars, popular cars from every generation that PD have forgotten or overseen or outright neglected. And they just keep adding on that eclectic selection.
When it comes to Ferrari, their is so many their is nearly every Ferrari, well not every Ferrari. But you get the idea. Eclectic again because T10 are so broad ranging in their picks. Same with Audi, Lamborghini, Mercedes, their is really a lovely selection, same with Ford.
Take BMW. You have the M1, the 850, BMW 2002, E90, 635Csi. All older classics among many other older classics not in GT. Plus you have the similar selection on top of that of cars which are in and aren't in GT.
Plus T10 are expanding on their McClaren list. Lotus was never strong with T10, but I hope that improves some day. Hope their are more Opel or Vauxhall in Forza too some day. But most of the car brands in Forza, you find cars that you, you family or friends owned as a youngster or coming of age, pre teens, teens. Cars to idol over.
T10 at least pick the popular and iconic cars. This is what I love about T10.
