I quite like that in Odyssey too - the ability to just wander off for a toilet break or something to eat. Then again, I also liked the fact that going anywhere alone at Alone was a death sentence (well, OK, I probably could have managed, I was tough).

So how does that help you? It doesn't, because you'll find that many players are the same as me and either a-awkward, or b-want the good points of both systems.

I think the important thing is how the setting justifies what you end up with. The Maelstrom murder game sounds dull to me, whereas in Alone there were really good reasons for the danger of the dark.
