Loot boxes have reached a new low with Forza 7’s “pay to earn” option - Ars Technica.
"Much like other in-game loot boxes, those in Forza 7 unlock random in-game cars and cosmetic items (and I'll get to those). But Forza 7 adds a peculiar and arguably non-essential twist to the loot boxes' random contents through a new item called a "mod." That might sound like an item that will modify a car to enhance its performance, but it actually modifies the circumstances of the next race—and, consequently, the amount of CR you can earn in that race.

Apply a "night race" mod to your car before a race, for example, and you'll turn your next race from day to night—and earn 30 percent more CR on that race. An "instability" mod turns off one of the game's "driver assist" perks in exchange for a 30-percent CR boost. Some mods don't count unless you complete an objective, like pulling off two "perfect turns" in a race. Other mods simply grant a flat CR reward boost in your next race without additional requirements.

Changing the difficulty or terms of a single race in exchange for a higher CR payout will sound familiar to Forza fans, because this used to simply be a standard thing you could do whenever you wanted. Players could manually add or remove certain assists—like "driving line" marks of where you should accelerate and brake—and get more CR per race for having fewer assists. That's no longer the case. You can still adjust the assists as you see fit, but you won't be rewarded for doing so... unless you have the right mod in your inventory."
