Mate a trading card game that integrated blockchain and NFTs? We've had a good number of those already and none really has penetrated the mass market besides Axie Infinity(though the hype already died down).
Yes, Axie Infinity was actually the pioneer in blockchain games niche to become an overwhelming success during the last bull run of 2021. The hype lasted for a while and many investors were able to recover their initial investments with a great profit margin. However, it doesn't prevent this WW2 game becoming a hot topic inside the niche this time... It will really depend on how much money is going to be injected on this project.
And tell you what — I checked the website of the game that you mentioned, and they're focusing on the token instead of the actual game lol. "Buy now".
There are many screenshots of the cards on the website as well. But if they keep insisting on financial speculation, instead of showing some solid gameplay, their success chances decrease considerably, as it will be seen solely as a greedy project ran to milk money from the community, instead of delivering entertaining content. People have to feel passionated about the game's mechanisms, just like players felt for Axie Infinity back then, especially the asian community who developed a deep bond with the game for a while, probably due to their cartoon's culture like Pokemon and similars.
By the end of the bull run of the year 2021 that was something I had learnt from projects like Axie Infinity, Plant vs Undead and many others. The developers got carried away by their Play-to-Earn marketing, they pushed it too far, making people to join their community and game based only on the possibilities of making money about of it, leaving to one side the most important things about a internet game: the fun factor. If they had left aside their marketing on Play-to-Earn and focused on attracting people who genuinely just sought to have fun with their multiplayer experiences, then perhaps all their tokens and the market would have not devolved into an speculative bubble like it did.
Nowadays it is possible to purchase axies at a very cheap price, when during the peak of their popularity one needed a minimum of 700$ or more to get three basic creatures to start in the game. I don't even know whether the project was abandoned or the developers continue to release updates and keep the game running, fixing bugs and errors.
One must be very careful if one ever considers to invest in a decentralized game in this context, as we approach a bull run, there will be many scammers seeking to jump onto an opportunity to take one's money.
