Magnanimous Composition Heroes: Rules of Heroic Games suffers from poor editing, layout, and as a product feels like a collection of house rules put to product quickly.
The pdf is 9 pages, with one being a title page and two being the ogl. That leaves six pages of content which was ok with for the price of admission.
The pdf uses a two column per page layout, but it is unattractive as there are spacing issues. In addition many pages have quite a bit of empty space. Normally I'd expect art in these voids or a redistribution of layout. The editing for clarity needs work as well as I found myself rereading the product just to make sure that I understood its rules as presented.
The internal numbering on the pdf isn't consistent, it appears that this document was separate documents brought together, and the page numbers were never updated. There are even two page zeroes, one right after the other.
The player option is a somewhat more powerful version of the gestalt rules, placing classes in tracks. This can result in a player taking a spell casting class twice and getting double spells known/per day. The product does say rules for heroic games and it certainly does give players that heroic edge, but gestalt did that as well, and the presented system seems to build on gestalt, not bring much new to the table.
The GM area presents rules for gestalt monsters for the heroes to battle and provides these options through what amounts to templates.
After reading the product I walked away with the feeling that the product was quickly put together house rules. Certainly OK for a free product, or as a handout to players starting a game with their GM, but with its layout problems, wording issues, and the entry fee its a no go.
Had this been a free product I'd have certainly been less critical, but this product left me feeling like I bought a handout that a GM normally just gives me as a player.
Note that the lack of artwork (other than the cover) was not a factor in the review, at a $1.00 price point I have no expectation of artwork.
Pros: Powerful PCs (builds on the gestalt rules)
Cons: Layout, wording, little innovation
