People are debating gambling these days. A lot of the focus is on prediction markets---but our youngest children are gambling in Roblox, not prediction markets. What values are we inculcating in our children as they inhabit their first algorithmic nation? For my latest blog post, @eigenstuffs and I decided to find out. We spent a week playing the 30 most trending games on Roblox. Watch the video below for a walkthrough of what we did and what we found, using MY MINING BRAINROTS as an example. What we found really surprised me. --Gambling-like mechanics are ubiquitous among the most popular games: the median game has 8! --Some of these mechanics are incredibly predatory. The worst is a "chained purchase" mechanic in which young children are enticed to spend digital currency to buy a good, only to discover that the purchase is just the first installment in an undisclosed sequence they must make to get the items they want. --The games all copy each other. They are not independently inventing these mechanics; rather, there's a shared underlying architecture of gambling being used by everyone. We conclude our piece with some recommendations for Roblox and policymakers. --Roblox should urgently experiment with alternative mechanics to help developers align on different, better models for designing and monetizing games. --Policymakers need access to systematic measurement of these bundles, and should take action to force transparency and potentially outlaw some or many of them. Lots more in our piece, linked in the reply below. Let us know what you think! We'll be doing a lot more work in this area.
