I previously made a suggestion here that aims to solve this problem in the long run, as honestly, “come and go” mechanics can negatively impact the future of this game, where they’re adding content, only to remove it later or rotate it.
The Horizon games took this to such an extreme with the Festival Playlist, and even Gran Turismo 7 has this with its Used and Legendary car dealerships, such as with the rotation of cars on sale.
Cars in FM8 like the Audi R8 V10 performance and Acura ARX-05 being time-limited are a few examples, and in the upcoming update, it would be the Lamborghini Sesto Elemento and Ferrari 488 GTB. It doesn’t matter whether it’s new to Forza, new to Motorsport, or even a returning car, no car should ever get left behind.
Turn Ten promised that there won’t be any things like a battle pass or anything like that, but with the cars being time-limited, it surely is something like one, except you don’t invest money, but rather time instead.
Situations may arise for players, with the common examples being work-life balance, or even another example being that you’re away from home and don’t have access to the game, that the likelihood of missing out on content is extremely high.
I’d rather have it in a way where if you complete these tours, you get a free car, but if these events expire, at least you can still buy and rent them.
Mind you, there are 528 eligible cars in the car selection for “Buy or rent cars” in Free Play, but the six exclusive cars and the Porsche 911 GT2 RS Forza Edition are missing from the lineup, bringing the true number of cars you can rent to 521.
