I forgot to mention this.
I do have a free demo for Machina and Magic. It is a little out of date, but it contains 25% of the entire base game and ALL of the core rules so you can totally play using it. The corerulebook is REALLY robust (475 pages) so trust me, you are getting a lot, even with the free demo.
