The Good - It's free. It's also funny, in places.
The Bad - The constant preteen humour gets forced and irritating after a while. The gods and scions are, quite frankly, useless. The blatant rip-offs of existing media topics stop being funny after five minutes.
The Ugly - It's a badly compiled file that can take minutes to go from one page to the next.
I love the Scion system, I really do. I own three sourcebooks, three supplements and four companions, all bought through DTRPG. This book adds nothing to the mythos that five minutes work and some crude jokes wouldn't replace.
The Scions, if you play them the way the book suggests, are largely more interested in getting laid than doing anything productive with their Birthrights (that preteen humour again). Seriously? A Professional Cat Herder?
For Scion completists only, and even then only if you need some Z-list NPCs and enjoy seeing "Adobe Reader is not responding..." error messages.
