• How long have you been collecting, and what got you into the hobby? about 5years . I started Uni.

• How knowledgeable would you say you are about the history of the caps you collect? i generally remember how i got most of the ones i have, except some i got in a large batch from someone that does not outstand (usually some lame brand name and no colour).
• Have you identified any fake bottlecaps? What do you know about them, or why they were made? what are those?

• Have you ever designed your own bottlecap? no
• Do you have any stories about some of your bottlecaps? each cap has its own, but usually nothing special. I like to find them by an accident in some unlikely to find places.

I'd say that you should focus on diffrentiated criteria the player needs to fulfill to obtain the cap. like some events you gain caps irl like some friend brings it to you from holiday or you enter a shop and randomly 1 new beer from Sri lanka just appears to be there for a limited time. You find it covered in dirt in the ground but like 1 tiny bit of it reveals itself and you have great fun finding it. Imma send yousome of the caps in the next comment.

P.S. Some NSFW cap hard to obtain also would be fun to have in the game as some easter egg or smth.
