I still don’t understand people who look at learning how to play a game like it’s work.
I can't speak to all of them, but to some... and Morrus, you're awesome, but you seem to like crunchy games, and that may be getting in the way of understanding.
There are players out there for whom
playing with the rules is not itself fun. The rules are a not-particularly-fun means to an end that is fun. For them, "work" is precisely what picking up a new set of rules is - an effort that isn't pleasant, that will hopefully eventually get them a payoff.
Asking them to pick up a new ruleset can be... like asking them to come to your house, where you will serve them a wonderful home-cooked meal. But first, they have to help you clean up the living room and dining room.
And, for a lot of games, what they are asked to learn... is a lot. Hours of reading. Trying to stuff a bunch of new stuff into their head that they don't really have context for, but they typically need to grasp without using it before they can even figure out what kind of character they want to play. Yeah, that's not a small effort for everyone. And it isn't fun for everyone.
Not small effort + not fun = work. Does that make it understandable?
