Construct 3 vs UPBGE

Construct 3 is a 2D game engine for building games with visual logic and optional JavaScript or TypeScript. Its event system lets creators specify behavior through conditions and actions without a conventional programming language; scripts can also be placed in events or separate project files. The editor runs in a browser without a download or installation and can also be installed as an app. A browser trial is available without an email address or registration. Projects can be exported to HTML5 web, Android and iOS through Cordova, and desktop wrappers for Windows, macOS and Linux. Construct works offline after its first load, though subscribers must reconnect at least once every seven days for revalidation. The Free Edition allows 50 events with a verified email or 25 as a guest, and limits publishing to web or Construct Arcade. Paid versions add desktop and mobile publishing and monetization options including advertising and in-app purchases. The Educational Plan is listed at $9.99 a month with a three-seat minimum; other listed license prices are not stated.

UPBGE is a free, open-source 3D game engine derived from the old Blender Game Engine and integrated with Blender. It supports real-time games, architectural presentations, robotics prototypes, physics simulations, and other interactive applications. Modeling and game functions remain in one Blender workflow, without importing or exporting assets between them. Projects can run in Blender’s viewport or as standalone executables. Logic Nodes provide visual programming with more than 300 nodes, alongside custom scripts and Logic Bricks. Python extends functionality, while GLSL supports custom shaders and post-processing. Rendering uses Blender’s EEVEE, with listed support for PBR shading, reflections, ambient occlusion, bloom, shadows, light probes, and volumetrics. Bullet supplies physics; Audaspace and OpenAL handle audio; Detour and Recast provide navigation. Runtime binaries export to Linux, macOS, and Windows. Compatibility is incomplete: Curves and Speakers are not rendered in-game. BGE games load and execute only partially, and UPBGE games may not run correctly in BGE. The project includes tutorials, examples, older releases, alpha builds, and a Discord community.
