I was considering starting a game with a more detailed combat system. Where sword forms and such are used. Perhaps where the player has a list of sword forms to use as attack, defense, multiple enemies, and duels. Rather than just roll and "hit" or "miss," the form that you use is good for offensive, or defensive etc, and can be countered with other forms. And how much you made or missed the roll by is taken into account. Are there any other games out there that have used such alternative combat systems that I can review, and maybe draw inspiration from? What are the downfalls of extremely detailed combat styles?
