You've talked extensively about Effort in many occasions by now, but there's still a piece of the puzzle missing, at least to me. How do you intend to limit rest in the Torment?
I mean, managing Effort is an interesting gameplay mechanic. but only because Effort is a limited resource. If players are able to rest whenever they want, the whole thing explodes.
Now, I know that during Cryses time is a factor, so resting will be either limited or impossible, but what about the "normal gameplay"? Will Players be able to rest freely in exploration mode?
Background: I explained the Numenera concept of Effort, and how we're adapting it for Torment, in our latest update here. Short version: Effort is a limited resource used to make difficult tasks easier. This resource can be replenished with healing or rest.
Alessandro, you are absolutely right (as are others I've seen around the internets who have expressed a similar concern): if healing is freely and easily attainable -- as it would be with a "rest anywhere" mechanic -- then Effort becomes meaningless. You could just use it all up on a task, rest to replenish, then use it all again on the next task.
So obviously the player will not be able to rest anywhere they want for free. You'll have quick rests you can use anywhere, but those are limited and they won't restore all your Stat Pools. Eventually your party will need to sleep. To do that, you'll have to find a place that will let you sleep for a price you can afford. Every Zone will have such a place, of course, but you won't be able to rest wherever and whenever.
Can you just head back to the rest spot in between tasks? Sometimes, sure. Other times you won't be able to get back so easily. Sometimes you'll need to do a few tasks in a row to accomplish something. And sometimes sleeping (which makes time pass) will have other consequences as well.
So sleeping will usually come with a cost. That cost might be trivial or it might be quite high. It will depend on what you want to do, where you are in the game, and what's more important to you at the time.
