OpenQuest reminds me very much of Chaosium's RuneQuest 2. Not sure why. Maybe it's the lack of endless tables that RQ6 brought into the mix.
In any case, OpenQuest 2 is the Deal of the Day. $7.50 in PDF, but that's not the sweet spot.
$14.50 in color Softcover, $22.50 in color Hardcover. Both options come with the PDF.
A complete and easy to play Fantasy Roleplaying game, with monsters, magic and exotic locales.
OpenQuest uses the classic D100 rules mechanic, which uses percentages to express the chance of success or failure.
This is the 2nd Edition of the game in full colour with 80 new pages of content. The Deluxe version of the game aims to be a self contained game with rules and advice on how to run a full campaign where the adventurers progress from their poor and ill experienced beginnings to the lofty heights of Godhood!
Open Quest is based on the Mongoose RuneQuest SRD (MRQ SRD), with ideas from previous editions of Chaosium's RuneQuest and Stormbringer 5th, mixed in with some common sense house rulings from the author's twenty years of experience with the D100 system.
