Marathon Map Editors
Mia - My personal favorite. Less features than Pfhorte, but the maps it creates have been proven to be very stable. Comes with tutorial.
Current Version: 1.0b17

Marathon Map Editor (MME) - Very user friendly and easy, although lacks all the features of other Map editors.
Current Version: 1.0d7

Pfhorte - A favorite among expert map makers. Has the most features of all the map editors available, however maps made by the PPC version of the application cannot be used on a 68K Mac. Some versions of Pfhorte have been known to create otherwise-safe maps that will crash.
Current Version: 1.0d25

New, version 2.0!

Pfhorte 2.0 is now a M2 map editor. See the M2 Map Editor Section.
Object Placement Editor (OPE) - A simple way to change the object placements in Network maps.
Current Version: 1.3

Marathon Edit Project - A simple map editor with the idea in mind that someone will improve it. Source code included. Not very good.
