This just means that we need a decentralized Steam platform, I do not know if it already exists but if it does not then that is a great area of opportunity and something that will be useful for a change, also we must understand that centralized platforms are often pressured to not accept cryptocurrencies and if they do to get rid of them at the first sign of trouble as governments are experts at dealing with centralized entities, so the creation of a decentralized alternative is more necessary than ever, even if I am not really a fan of those games.
Silberman, it sounds great, but I don't think that it would work without a huge financial resources, that you need to invest in such a project. And in that moment - it would definitely lose in it's potential decentralization.
