Unity will adjust the runtime fee that requires developers to pay to install the game. For example, there will be a maximum payout of 2.5 percent, games with a turnover of less than $1 million will not have to pay anything and existing games will be excluded.

The game engine maker says the runtime fee will only apply to games using the next LTS version of Unity. This version should be released next year. Games shipping now that developers are currently working on will not be subject to runtime fees. Emphasizes unityProvided that the developers do not upgrade the project to the latest version of Unity.

The company also says it will increase the trading threshold. Previously, only games with annual sales of $200,000 were exempt from the runtime fee, but now it will be $1 million. Uptime fees will also be capped at 2.5 percent of total game sales. There were already rumors about this limit, but then it was about 4 percent.

Runtime fee is the amount that developers have to pay every time a user installs a game on the device for the first time. Unity sees the fees as an additional source of revenue, on top of the amount developers already pay for the game engine. The company announced the fee last week, which quickly drew criticism from game makers, in part because the fee would also apply to existing games. The fee should generate $0.20 to $0.005 per installation of Unity, depending on the number of installations; Few installations cost more per installation than they do with many installations.

Unity CEO Mark Whitten apologizes for the course of events and lack of communication prior to introducing the runtime fee. Whitten says the fee allows Unity to continue investing in the game engine.
