It is not allways easy to find people for a good long RPG campaign that will last for a month or longer. Therefore, unlike the wargames, I like to play my RPGs solo.
Therefore, my system of choice for noncombat encounters is definetly Mythic RPG. The only problem is that combat resolution with this system can be a bit boring.
Well, that is where WHA&A, mixed with free Chain Reaction 3.0 Swordplay (featuring somewhat improved mechanics) comes into action, becoming my system of choice for combat encounters. Reaction mechnics for controling NPCs in combat is just revolutionary.
What I like: Combat magic, Reaction system for NPC control.
What I do not like: the book is few years old, and has to be updated using CR3 Swordplay for optimum results. Having this in mind, 20 USD is too much. New edition or price reduction should be in order.
