As you can see on this pie chart most of the revenue from selling ingame items will go back to players trough Soul token. Because this is a Cross Chain game it is bound to have more players than any other crypto game, I don't think something like this has never been done in any crypto game before. There is a lot of strategy involved and it could be big, it is already going strong with the player base.
Considering this game just came out you can see on ddap review the volume of every all three cryptos that are being used- Ethereum, EOS and Tron. The main driving force is the Soul token. Interesting innovation for one crypto game for sure.
Some interesting stats:
Daily volume on EOS for this game is 10 times higher than any other game, daily volume on Tron is higher than any other game, only Etherem is lagging behind (probably low number of people heard about the game in their social circles). All this is telling a lot, there is hype behind this game and it just started.
ChainZ Arena launched just 4 days ago I see no reason why the devs of the game couldn't implement more blockchains in the future, Hive for example, there are a lot of Hivers who would jump on this one.
