MegaZeux (or MZX) is a game creation system (GCS) initially released in late 1994 by Alexis Janson. MegaZeux is heavily inspired by Tim Sweeney's ZZT. Like ZZT, MZX was originally released as shareware and the world editor portion of the program was included for free, allowing third parties to create their own worlds without even registering.
MZX is officially supported on Microsoft Windows, Mac OS X, Linux, FreeBSD, OpenBSD, Android, Nintendo DS, 3DS, Wii, Switch, and the PSP. Older ports exist for AmigaOS 4, GP2X, and Pandora. MZX has also been ported to other platforms such as OpenSolaris, HaikuOS, and the Sega Dreamcast.
