I wasn't sure what Undiscovered would be like, but after reading 1 or 2 reviews (and the £3.16 price), I thought I'd risk it.
370 pages long, many charts and tables.
The artwork isn't too bad.
At character generation, you can either use points or random method.
Skills go through initiate, novice, adept, expert & master levels (which cost points).
It has a good history/background, and some interesting monsters & races.
You can download the maps at their website: www.eilfin.com.
All in all, rather good for £3.16 ($5.00).
