I watched your video and you talked about the photos holding value, how do the photos hold value in the future? I don't understand how you can make that statement, could you give me more information?
It's an interesting system you are creating.
By value, we mean the card's "perceived value" in the wider in-game marketplace. Due to scarcity, some cards will be rarer than others and will therefore be more valuable, thanks to principles of supply and demand. Owners of these rarer cards will be able to negotiate better trades for the cards they still need to fill up their album.
