I really don't get this impulse of wanting devs to hand their projects off to a rando to finish? They won't make anything close to what the dev had in mind unless they either have the script, or worked closely with the dev and are intimately familiar with the project. Look at Bad Bobby Saga. It's spawned a million shitty spinoffs. The one decent one has been rebooted like 3 times and isn't really even the same game. Just let games die and new projects take their place.
