With Mobile Frame Zero in it's infancy, it can be hard to find other people to gather around the table and roll dice amongst a selection of Lego mecha. This has been an issue with players of other games as well, including the ever popular Dungeons and Dragons, and tools have been created to facilitate playing them over the internet.
MapTool from RPtools.net is a great piece of software for accomplishing this task. And thanks to Sagethe13th and FeralFerret over on the hanger, it is now an option for MFZ as well. I've been involved with a game or two using this setup and I can honestly say it's really smooth. There is a bit of fumbling about at first but the learning curve is shallow.
You can download the "MoFo" campaign file which has all of the macros and such here. I will be putting together a tutorial on how to setup and play a game using this system in the near future.
