Unity has recently changed its pricing model, shifting from a pay per seat system to a pay per install model. This has significant consequences for developers, especially in mobile gaming where revenue per install fluctuates greatly. Unity is now charging $0.20 per install after the app has made $200,000 in the past year, meaning users will need to see at least 10 ads after downloading the app to avoid incurring costs. This change is retroactive for existing applications as well. Open source game engines like Godot provide protection for developers, granting them rights to the engine that cannot be taken away or altered. Ramatak Mobile Studio enhances the open source Godot engine for mobile games, offering ads, in-app purchases, and analytics. Developers have the option to switch to the open source version if they are uncomfortable with any changes made by Ramatak. Using an open source engine ensures developers have the freedom to take advantage of new gaming trends and dictate their own monetization strategy. With Ramatak, developers have the best of both worlds: the security of an open-source engine and the tailored features required for modern mobile games.
