Mecha G-Core is essentially what it says: a mecha add-on for the G-Core system. There are some good ideas here, but it isn't as complete as it could be. Not all of the ideas discussed are given examples.This is, more accurately, the framework, a solid framework, but a framework.That being said, in characteristic "Jay" fashion, Billy Green Bean Games is posting a series of free PDFs to its website addressing some of the lack of examples and explanation. Beyond that, this PDF is only a dollar. I shouldn't say "only a dollar", but most of us don't even get our morning coffee for that little. With a little creativity, some of the concepts within this framework can easily be adapted to Icons or the old tried-and-true Marvel Superheroes.
