Playtron is coming out of stealth with $10 million in funding, roughly 18 employees, and a plan to challenge Microsoft, Valve, and Apple for the next hundred million gamers. It starts with a Linux-based operating system that plays Windows games, just like the Steam Deck — except this one isn’t tied to Steam. But within a year, Playtron believes it’ll be competing with Windows as the OS for gaming handhelds.
