I don't think "narrative focus" is a requirement for rules light games, and some narrative games (like FATE) can be quite crunchy.narrative focus over defined, detailed mechanics.
Light: Few, but easily rememberable and interpretable rules.What do you consider a "rules light" RPG and what do you consider a "crunchy" rpg?
I am not sure. Light and Crunchy are pretty subjective terms.What re the parameters?
A good example of a crunchy RPG is Pathfinder 1st edition. PF1 leaves very little up to interpretation when it comes to covering every aspect of the RPG. It wants to very much inform the GM and the players on what they can and cannot do during an adventure. However, the downside to this, is that it requires both to constantly reference its' material.What are good examples of either?
5e D&D and Level Up.What games hiot the sweet spot for you as to level of light versus crunch?
It seemed time.Is it this time again?
You don't think there is a continuum of difficulty to learn, where there must be come games in the middle?Lastly, I dont believe in rules medium. I think folks that are gamers forget their decades of experience has led them to quickly absorbing rulesets. Especially, those they have familiarity with like D&D.
I really dont. Im also speaking in generalities on purpose. I know different folks learn at different speeds. I also know page count doesnt mean anything in a vacuum.You don't think there is a continuum of difficulty to learn, where there must be come games in the middle?
