I’ve always allowed players to jump in with the Aid/Interfere move after seeing another player’s roll and it’s never caused problems. But in last Saturday’s one shot game, players declined to help each other on numerous occasions after seeing that granting a +1 would not change the results.
An easy way to address this is to simply say players have to make the Aid/Interfere move before the target rolls for their move. That could still be a bit unsatisfying though, as successful help might still not do anything.
Has anyone tried changing the Aid/Interfere move so that it increases or decreases the effect level of the target’s roll? Turning a 7-9 into a 10+, for example. If so, how did it go?
