Different rewards system

Every day it gives us like 15 new challenges, and every challenge pays the same. The boxes have different prices but there's a set amount, you could do the math and come up with a total to buy every box, then divide it by your daily payment from challenges and come up with an exact date that you'll "beat" the early access.. if the whole game is like this I can figure out the exact completion date on day one....  A really bogus "achievement" that, no matter how hard you grind and no matter how good you are, you still have to play the waiting game; and after like 15 years, that's the last thing we want to do with a new skate game. (Especially if we can already log in and run around)
