Robot Cache, a Steam rival that lets you sell your 'used' games and mine cryptocoins, opens signups

Steam alternatives are cropping up all over the place, so let's throw one more into the ring. Announced earlier this year, Brian Fargo's Robot Cache officially began signups for its so-called Early Access period today. Well, players can sell used games, developers get to keep 95 percent of a game's revenue, and there's a cryptocurrency involved. If you go to the Robot Cache website, it even says it's "The world's first blockchain-based digital marketplace for video games." The cryptocurrency in question is called "IRON," all-caps, and apparently one Iron is pegged to the value of one Euro.
