The Mythus system is complex, but a compatible system might be less so. Part of the complexity of the system was due to the great lengths taken to distance the system from AD&D, which makes the whole law suit laughable. In creating a new system, many of the new terms could be replaced by more familiar terminology. I think the new vocabulary was responsible for intimidating many potential gamers. Also, the original presentation was information overload. Shooting for just the Prime rules as a starting point might make the task less daunting.
