Cross The Ages (CTA) is a blockchain-based collectible card game. You play using digital trading cards that are also non-fungible tokens (NFTs). These digital cards can be converted into physical cards if you wish.
The game is set in a dystopian future based on a series of seven fantasy and science fiction novels. The first book, "Artellium," is available online. Players compete individually or in teams, earning NFTs and other digital assets through gameplay.
CTA's unique aspect is its "phygital" nature, which bridges the physical and digital worlds. You can collect cards digitally and physically. The game also features an in-game economy where you can trade, lease, and sell your assets.
