i built a card game that turns wikipedia into 55k collectible cards
solo founder, launched at the end of september.
the idea: every card is a wikipedia article and rarity comes from the article's real page views, the 90 day median. a pipeline keeps adding cards from wikipedia, about 55k so far. once issued a card never changes rarity, so early cards stay what they were.
what's in it: packs, families and albums, kosmo earned per hour from your collection, an auction market, trades and gifts between friends, daily challenges, and a gamemode
stack is next.js, fastify, postgres. it's a pwa, english french spanish.
money only buys cosmetics. no packs or cards for money, i didn't want pay to win.
ai disclosure: card text is summarized by a language model, some pictures are generated.
