Details: The new "Runtime Fee" announced Tuesday morning is tied to a player's installations of a game, an action that previously didn't cost developers anything.
- With Unity's new plan, developers who use Unity's free tier of development services would owe Unity $0.20 per installation once their game hit thresholds of 200,000 downloads and earn $200,000 in revenue.
- Developers paying over $2,000 a year for a Unity Pro plan would have to hit higher thresholds and would be charged with lower fees.
- The newfee system will begin at the start of 2024.
