Hey i got another idea
Why not among pass, like a battle pass
Why would you want a battle pass instead of free skins, pets, hats. 1. you will have to pay for ingame cosmetics. 2. people will do the challenges and then leave games or if its to Sabotage Reactor 10 times the Imposters will use Reactor instead of lights which can impact the game. 3. Among Us is supposed to be simple not Fortnite where almost everyone buys the battle pass and whale on the game.
