I personally sell the packs at a “card shop”, and have it set so you craft specific groups of cards into badges, and then craft the badges into a trophy which players can sell for a high value.
This has been in use in my server for months “Leviathan Roleplay”.
example “recipes” will be included in RECIPES text file.
so you put packs into shops, you can open packs to get a card/cards then you use the cards to build badges? How close am I to the mark here? This sounds amazing, how do you build sets?
