I can buy almost all Mongoose Legend supplements but want to optimize shelf space to only those that would be very useful for my Mythras collection for historical non-fantasy or low-fantasy roleplay. Currently, I am focusing on these books but unsure about their authenticity and quality of historic material.
Vikings of Legend (black cover)
Pirates of Legend (black cover)
Samurai of Legend (black cover)
Need advice on the usability of the following supplements:
Arms of Legend (black cover) - how directly usable the information on weapons is for Mythras (being RQ2 vs RQ6)
Monsters of Legend I and II (black cover) - how compatible these monsters are for use with Mythras, what would be their balance (too easy, too hard)
Gladiators of Legend (black cover) - I noticed that it is heavily fantasy oriented, but wondered if anyone finds it useful for standard campaigns (esp. with Mythic Rome).
Arcania of Legend: Blood Magic and Elementalism - are these compatible with Mythras, and what is the quality/balance of these systems in comparison with Mythras magic systems.
Finally, what are the differences between the black cover editions and the actual color cover editions called "revised", is there a reason to hold off on buying the black cover editions? Mongoose seems to only sell them on their PDF store.
