Ok I'm going to re-write this

 In games YOU have been in, or which YOU have run, do YOU remember any particular experiences of;

- Too many options, not enough direction, decision paralysis.

- Sense of a loss of freedom, a muting of interest, feeling like you are just "going through the motions"

- Any "just right" states where the range of presented options and possibilities synergised really well and seemed to both guide and allow play.

In those situations;

- Can you describe the situation as it occurred?

- What games were they? (if it published adventures you don't have to name them if you don't want to.)

- Did you notice anything about the adventure design that made them that way?
