Coriolis
Coriolis products stand at the intersection
of the Open Game License and our other roleplaying game
titles. Each is a dual-system adventure that use both the SRD rules, and the rules of one of our other game lines so that you can sample our other games without
worrying about unfamiliar systems. If you're a long-time
fan of our other game lines, these cross-over titles will
give you an idea how to bring elements from
Unknown
Armies,
Rune,
Ars Magica, or
Feng Shui
into your OGL game.
Each of our
Coriolis products is a
stand-alone product. Every book is all-new, so there's something for new readers and faithful readers alike. All the game mechanics and "crunchy bits" are expressed using both the SRD rules and the rules native to another Atlas Games line.
What Coriolis is not is conversion rules to adapt other game systems into the SRD rules. In many cases, the rules of a particular game system aren't translatable into the OGL lexicon -- that's why the game designers worked so hard to develop their own rules in the first place, after all. The parallel rules sets found in Coriolis avoid the complications that would inevitably break conversion rules. However, where possible we do try to recreate the flavor of the non-OGL game in Coriolis.
Think of these books as short trips into other
game worlds. Each one tells a compelling tale that could
serve as a short side adventure or be adapted into your
current fantasy campaign with a minimum of effort.
Coriolis titles teach by example. By
following the lead set in them, you'll be ready to adapt
material from any Atlas roleplaying game to work with the SRD rules, and you'll understand how those
books can enrich your OGL adventures.
