An Alternative for Skill Challenges

Collaborative and narrative play are more my jam when it comes to roleplaying games. I like to leave breathing room for the players to be creative and inject something into the narrative within the confines of moral dilemmas and hard choices. Back in my Dungeons and Dragons days I made heavy use of skill challenges for action scenes as opposed to always using the combat game structure. This allowed me to confine my players to a particular situation whilst providing the aforementioned breathing room. However, I did find skill challenges had the danger of becoming too 'control panel' for my players so to rectify this I wanted to change the way players interacted with the mechanic and adapt to other d20 systems that use the 6 attributes but potentially not skills.
