The original conversion did start that way.I think you should start with "I'm not having fun. I think everyone at the table should have fun. What can we do to make this fun for everyone?"
Without that conversation, no system is going to solve your group's problems.
Me: "Hey, in a few months we'll be getting to a natural end of the 4e campaign. Half our players are going off to college, so I'd like to end that campaign on a high note for them. After that, we can transition to a game that's less prep for me that works for fewer players, more story driven?"
Them: "Well, what would you like to run, since you've been putting in so much work for these games?"
Me (after a month): "Here's a list of some games I'd like to run."
Story driven player: "I'd rather not do Call of Cthulhu...."
Me: "Enough said. I'll cross it off the list."
Me: "We've wrapped up the 4e game. Let's have few weeks of one shot indie games with the college kids before we start a new campaign."
Me (to the story driven player): "Here's the basic rules for Dragonbane I picked up at Free RPG Day. See what you think."
Story driven player (over the next week, through texts and in person): "I'm excited about Dragonbane. Seems to be something I'd like."
I know my wife had plenty of time to learn about it. She's been subjected to me listening to videos and podcasts about it for months. I've talked to her about considering it for weeks ahead of time. I told all the players it was more dangerous, survival is a bigger issue than other games. I really don't know what more I could've done. They just didn't care to learn about it (with the exception of the story player).
