GtkRadiant vs Mega Man Maker

GtkRadiant is a free, open-source level editor and toolchain for games powered by id Tech engines. It includes map compilers, data authoring tools, and Q3Map2, with tools for 3D levels, terrain, and entity placement. The GtkRadiant 1.6 page lists support for games including Quake III Arena, QuakeLive, Urban Terror, Wolfenstein: Enemy Territory, Quake2, Quake2: Remastered, Quetoo, Return to Castle Wolfenstein, Star Trek Voyager: Elite Force, and Jedi Academy. Support for a game can depend on an active developer to test and address issues; some titles may require an older version or third-party fork. GtkRadiant reads and writes assets in a game's directory, and the project recommends installing the game first. It runs on Linux, macOS, and Windows. Linux distribution is through Flathub as a Flatpak; the Mac version requires XQuartz, MacPorts, and other dependencies. Volunteers maintain the GPL-licensed project, which is provided as-is without warranty or support. Listed help options include forums, IRC, tutorial sites, and a GitHub issue tracker.

Mega Man Maker is a free fan game for creating, sharing, and playing user-made Mega Man levels. Its Level Builder lets creators assemble two-dimensional stages and save them as .MMLV files. Build Online supports real-time collaboration over the internet. Before uploading a level to the online server, its creator must beat it; accounts can upload up to 420 levels. Players can browse, search, sort, download, like, and dislike uploaded levels, or play Wily Challenge mode. The builder has space for 1,000 screens in a 50-by-20 layout, though listed asset counts are marked outdated. Players can report levels, and moderators have tools to handle reports, including those about offensive or unbeatable levels. The game runs on Linux, macOS, and Windows. It is a non-profit fan project unaffiliated with Capcom. The official homepage lists version 1.10.5.4, dated 24 August 2026.
