A while ago I stumbled upon Mechanical Dream. While I found it rather interesting, my group at the time was not so keen on playing, and we rejected it. Since I liked it a lot, I am asking if there is any document, PDF or website with the game's rules gathered and woven in a fashion that is relatively easy to understand. It consists of two core books: one that seems to be a (pretty confusing) rulebook and another one that's more roleplay oriented and introduces some basic ideas that seem to be a big part of the game.
The core Mechanical Dream rule book Mechanical Book is back in print in PDF from SteamLogic on DriveThruRPG.
The Dream Book PDF is also available there.
A quick Google search revealed a few reviews but no web sites dedicated to the game itself. As the game is out-of-print and SteamLogic, the publisher, went bankrupt in 2004, the chances of finding it are pretty slim.
There is a boxed set available on Amazon.com but it's priced at $200.
So the answer to your question "are the game rules available" would, unfortunately, be "no it appears they are not".
