Parallel one of the unique trading card game in the niche. And the game allows better control of the in game items and the NFTs that are being sold through the cards and the in game. It's one of the games that seems to have a potential in near future. Though plenty of card games come and go but we have plenty of things that they do wrong and often not really stay relevant as the time goes.
It's been early times for the parallel on that but they seem to be making some progress.
There is a planetfall expansion going on. And they are planning on releasing the 180 new cards into the same. If the team does the testing and tweaks you would be able to see more numbers coming out based on how they expect to handle.
Game has five factions and basically you fight in the game for resources. And that's where the TCG game approach comes into the play. I would have loved it if they make it some single player game. But then again those games are not popular in the blockchain space like the TCG is and so they seem to be pushing the TCG angle more.
You can take a look at the gameplay.
