"Coupon Book Stick RPG 2" – Not a Real Game; Design Ideas If You're Creating One

No game by that title exists. If you're designing one, coupon books could be:

• Currency – trade for items/services.
• Quest items – collect specific coupons to unlock area.
• Buff tokens – temporary stat boosts.
• Comedy mechanic – haggle with NPCs using expired coupons.

Settings: fantasy market, cyberpunk black market, post-apoc barter economy. Get creative!
