Valve has banned Blockchain and NFTs from being available on Steam, but Epic Game is trying to get it back to its store.

Games using Blockchain technology or NFTs or cryptocurrencies will no longer be allowed on Steam. Steam is the most popular PC game store. While Valve has banned Blockchain and NFTs from being available on Steam, Epic Games is trying to get it back on its store.

We chose to be upfront about blockchain gaming & NFTs. As a result, we finally lost the battle with Steam. While I'm disappointed for Age of Rust being removed, the point is more to the fact that Blockchain games as whole are going to be removed. This is setback for all.
