problem is most people don't like replaying the same thing over and over to see all angles of what could have been. There are some who do. My middle son played skyrim til he had done everything in the game multiple ways with multiple characters. Each of those characters spent more time in game than my one did.I've got the thing for you: Eamon-remastered.com. Make your character, pick your quest, play it through, take home loot. Want more? Play it again. Try that idea you didn't try the last time. See what happens. Or make a different character, put it through the same quest.
I've been working on the DRPG version of it, but . . .
. . . it also doesn't self-implement. So it's moving along at the One Amateur's Production Speed. But I really like the concept, because sometimes you don't want a campaign, and don't care if the Quest-Giver gets his farm back, or the Rogue's long-lost brother is rescued. But that last quest sure was a blast, and it might be a whole new experience if a different party tried it.
but that kind of play is an outlyer. Most people want to be surprised and aren't going to play the same game multiple times to see what all the options could have done.
