What does the new wave of open economies mean for monetization? Will negative externalities overcome cosmetic economies in the long run? What exactly does a game economist do?
Game Economist Cast is a roundtable discussion of the latest developments in mobile, HD, and crypto games, through a bunch of people figuring it out using the economic toolkit.
E50: Predication Markets in Roblox Replacement Theory? Did Malthus Really Lie?
Roblox's generational numbers will change the face of gaming forever, but no one seems to give a shit. Phillip Black, Christopher Kaczmarczyk-Smith, and Eric Guan sketch the Malthusian arithmetic behind Roblox replacement theory and what it all means.
We turn Polymarket into a one-dollar group game and compare the economics of $40 rhythm games and Elden Ring DLC.

E49: The Economic Game Theory of All Games
The entire theory of games is underpinned by this one theory, but how far can it's explanitory power be pushed? Phillip Black, Christopher Kaczmarczyk-Smith, and Eric Guan talk cozy Pokemon habitats, merge-game economics multipliers, AI labor-market irony, and Edward Castronova's foundational work on virtual worlds.
We talk:
Pokopia as the Pokemon cozy game:
short production chains
daily-quest systems without free-to-play monetization pressure
Multipliers as the key merge-game innovation:
a gas pedal on spend per hour
faster energy drain
faster story progression
a new way to price acceleration
Narrative as reward subsidy or tax:
story can make the next meta milestone worth chasing
story can also break flow for players who just want the core loop
AI and the game-industry labor market:
layoffs look more like a post-2021 correction
longer unemployment spells in information work may be the cleaner AI signal
AI may suppress hiring before it shows up as direct separations
Castronova's virtual-world economics:
challenge
labor-leisure tradeoffs
property rights
platform dictatorships
price controls
why MMOs looked like the future in 2003
The player contract:
games rarely grant formal property rights
players still behave as if they own skins, items, and progress
developers often compensate players even when the legal right is weak

GEC BONUS EP: What's up at GDC 2026?
Takes so hot that they were recorded late at night after a long day on the GDC floor, and couple whiskeys. Phil, Eric, and Chris crew unpack what actually mattered at GDC 2026, and what didn’t.
We discuss:
A sharper critique of industry thinking
Too many taxonomy talks, not enough opinions
Why game talks should behave more like economics seminars
AI’s role on the show floor and conference
Shift from generative art hype to code generation and workflows
Why survey data understates actual usage and masks revealed preferences
AI present but muted, Web3 effectively gone
Novelty hardware, indie creativity, and a clear tech pullback
The collapse of production costs and what replaces them
Near-zero fixed costs leading to infinite content supply
Discovery, marketing, and CAC as the new binding constraints
Why incumbents may strengthen, not weaken
Ad spend and distribution advantages widening the moat
Counterpoint: new channels still create pockets of disruption
Hardware, interfaces, and “convergent evolution”
Why controllers standardized and what that says about optimal design
Failed alternatives and the persistent friction of interaction
