My friends and i have a dumbass brain. And we love to blow loads of cash on Moxxi’s slotmachine in Borderlands (you guys know that game right?) And then we forget to buy ammo/health and laugh as we get caught empty handed by bandits who will be salting our wounds in due time. what about adding a slotmachine in this game that eats unwanted gear as payment then pukes out new gear for you to feed with. The rarity being based on the amount and rarity of the gear your willing to sacrifice. Add slotmachine coins to loot crates found throughout the game that allow free spins to encourage use of this mechanic. Maybe make the coins off different rarity aswell or coins that only allow specific gear to be rewarded.
PS: PULL THE LEVER!
