Adventure Game Studio vs Defold

Adventure Game Studio is a free, open-source IDE and engine for creating and running point-and-click adventure games in the style of classic Sierra and LucasArts titles. Its editor is supported only on Microsoft Windows or Windows emulators such as WINE, while games can target Windows, Linux, macOS, and Android. The Editor includes a component for preparing Android builds, and AGS Player runs compatible games on Android. The runtime engine also has ports for iOS and a web version that runs in a browser when served from a web server. Plugins can add game functionality, but a compatible plugin build is needed for each target platform. AGS was created in 1999, became open source in 2011, and is developed by contributors under the Artistic License 2.0. Its terms say the software is provided as-is without warranty and prohibit charging money for AGS without written permission from its authors. The manual recommends community forums for development help.

Defold is a game engine for building cross-platform 2D and 3D games. Its toolchain combines an editor, runtime, scripting workflow, build pipeline, and deployment flow. Game logic is written in Lua; native extensions can use C, C++, Objective-C, Java, or JavaScript. Visual editors, a debugger, profiler, particle effects, animation, and integrated 2D and 3D physics are included. Target platforms listed are Windows, macOS, Linux, iOS, Android, HTML5, PlayStation 4, PlayStation 5, and Nintendo Switch. Integrations include Firebase Analytics, AdMob, in-app purchases, push notifications, Google Play services, Nakama, and PlayFab. The Asset Portal offers reusable components and extensions. Live Update can provide additional game content after the initial download, with customizable content verification. Source code for the engine, editor, and build tools is available on GitHub under a developer-friendly license derived from Apache 2.0. Defold costs nothing, with no licensing fees, royalties, or runtime fees. Community help is available through a forum, and technical support contracts are available if needed.
