Upcoming blockchain-powered PC games storefront is going to have a careful content policy.

That's according to CEO Lee Jacobson, who said we weren't going to have school shooter titles - like another prolific platform - on its marketplace.

"We're selective. The store is going to be curated. There are going to be no school shooter games, nothing like that at all on Robot Cache," He said.

"I wish I could tell you the exact approach about how we're going to do this, but right now we're going to look at all the games. Every game that gets submitted will be reviewed for content. You can put anything you want on Steam - people can download Unity assets of two characters fighting, put that up for $0.99 and call that a game. We're not going to put that game on Robot Cache. I'm hoping we can learn and have a good curation process over time. I don't want people looking through 70,000 titles."

As well as using blockchain tech to track individual games - meaning they can be safely resold - Robot Cache also allows users to mine the Etherum cryptocurrency and benefit from the rewards. This is an opt-in decision, rather than opt-out, with Jacobson saying that it's important to be clear about what's going on.

"We've seen certain stories where certain browsers get hijacked with people downloading viruses and, without the user's permission and making them part of a massive client mine pool which is bullshit," he said.

"It's caused a lot of problems for a lot of people. We took the opposite approach, which is opting in rather than opting out and when you opt-in, it's going to clearly tell you that Robot Cache is going to mine Ethereum on the backside, convert that in bulk into Iron and that goes into your wallet. You can spend that on a new game. It's up to you. That was really our focus."
