Mega Man Maker vs NetRadiant

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 The builder has space for 1,000 screens in a 50-by-20 layout, though listed asset counts are marked outdated.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.

NetRadiant is a free, open-source 3D game level editor that uses brushes to build levels. It has first-class compatibility with Xonotic and Unvanquished and supports about 30 other games, with support varying by game. The project is driven by Xonotic, receives support from Unvanquished, and is maintained by a community of gamers, mappers, modders and game developers. It originated as a fork of Id Software’s GtkRadiant project. Listed downloads include Linux 64-bit, Windows 32-bit and 64-bit, macOS 64-bit and FreeBSD 64-bit builds. The builds include daemonmap for Unvanquished navmesh generation and q3map2 patches for Smokin’ Guns. Released Xonotic files work without an extra mapping support package. Linux use requires a working GTK2 and OpenGL environment. Windows builds offer optional Mesa3D rendering, described as a workaround for some older Intel chips on Windows 10. A 2022 project post described macOS support as new and potentially rough, including possible multi-screen configuration problems. The download page lists version 1.5.0-20220628.
