Steam has been one, if not the only, biggest digital game platform for the PC, where most developers put their new and upcoming games for sale. While it has no direct competitor in the past years, it looks like there is a new digital platform on the block, and it has been getting a lot of attention recently.

The new digital platform is called "Robot Cache." It will mainly serve the same purpose as Steam, which is to sell games. However, the main selling point for Robot Cache is that it also allows players to sell their games once they have finished it. Simply put, it is like where players can buy second-hand digital games. One new thing as well is that it is blockchain-based.

The platform was first unveiled by InXile Entertainment CEO Brian Fargo. "Just a handful of companies dominate the multi-billion dollar digital download PC video games market," said CEO of Robot Cache himself, Lee Jacobson. "Robot Cache plans to revolutionize the industry by launching the first-ever workable decentralized video game marketplace that benefits both the creators of video games and gamers. All of this is accomplished by expertly leveraging the power, flexibility, safety, and transparency of blockchain technology."

Robot Cache will additionally have its own cryptocurrency called Iron, which can be gained by either mining or reselling games. Players can even decide to cash out Iron if they want to.

Unlike GOG.com and Steam, who get 30 percent from sales, Robot Cache will allow developers and publishers to keep 95 percent of their revenues. People who resell, on the other hand, will keep 70 percent.

There is no exact release date as to when Robot Cache will be out. The release window, for now, is set to the second quarter of this year. Regarding the games it will offer, they promise to release the latest games in the market.
