I ... I think that my players are modern players? They certainly play now. Some of them are relatively new
Some of them take the average because they want to have consistent, predictable hitpoints.
Others roll hit points because they want the chance to roll high- just like stat rolls.
Players like to roll because they think they might roll high. They don't really like it when they roll low.
So... might as well just take the average- or if players
really want to roll, adopt something like WWN's system that'll help the gamblers among them to not wallow in the low end of the pool.
Or.. you do you. The casino analogy was just that: to show the situation in a different context. No need to make judgements about what makes a "modern player."
