ALSO TO EXPAND ON THIS. Different groups could be divvied into different types of tasks.

Ie: Group A is exploradora, you have to find your way from point 1 to point 2
Group B is AN ANAGRAM/PUZZLE, figure it out to unlock a treasure chest
Group C FIGHTS MONSTERS
Group D interacts with an NPC?! must convince the NPC to do xyz thing

This would give players more opportunity to opt in to whatever group best suits their play style and character abilities.
