In PlayIndex, games are the stocks. Every price is driven by one number: how many people are actually playing that game right now. Live Steam concurrent player counts are pulled every 10 minutes and turned into a market you can trade. No fictional companies, no invented charts: when a game blows up on a Friday night, you watch it happen on the tape. Build a portfolio out of games you think are about to catch fire, and sell before the hype fades.
