It's a lot of racial feats and support for the Dawnforge Racial Talents system. I like the system so I enjoyed the book a lot. There is some fluff for each race, but it's basically a Races Of book for Dawnforge.
I really enjoyed this book. You get more options for racial talents and transformations. The races are fleshed out more, too, so you get a better feel for them. I thought it was well worth it at full price. $5 is a steal.
yeah, I was looking at the Dragonstar stuff because I have a friend who eats that sort of thing up. Unfortuantely, the core book is the one not available.
I bought the 3 Fireborn books for 15$ I've been interested in them for a long time so that's cool.
I have the Dragonstar books (bought the collector's edition set 2 years ago) and I half-heartedly recommend it. The books are good and interesting, however the mechanics are outdated (heavily 3.0) and I didn't see any use in them yet.
Dawnforge is awesome. Rather than playing long after the mythical "age of legends," you get to play in the middle of the legendary age. It really does a great job of making the PCs feel like they are or will be legends. Many of the standard D&D stories are there (elves vs. dark elves, dwarves vs. giants), but they are in their infancy. You feel like you could actually have an effect on things because they haven't always been like that. I highly recommend it.
For those interestedin Dragonstar - get the Guide to the Galaxy book. It has great background material. For the rules stuff (which the Starfarer's Guide mostly is) I'd use d20 Moder/Future or maybe even d20 Star Wars. Heck the way the Starfarers Guide is set up you just port over the core classes from the 3.0 PHB wholecloth anyways so i never saw the poitn in the book (they do add a bunch of skills and feats but d20 Modern does this in a much mroe complete fashion). The Guide to the Galaxy book is the meat of the setting (and I really do like the setting just hated the 'crunch' that went with it).
