Just bought this game an absolutely adore it. Great, simple and thematic rule system!
My only real complaint is that it contains just one "scenario" (rainforest plane crash) where I think two or three (island shipwreck, arctic expedition gone wrong, etc.), would help "sell" the concept better.
That said, the huge amount of flexibility in setting makes coming up with new stuff a breeze; I've already developed a fair bit of homebrew for it and am writing up more right now!
One big question regarding the rules, though: how would a "hunt" under the vanilla rules work? For example, if a player is hunting a deer? If a player has the Hunting skill, they'd normally get a +2 to their Challenge rolls... but the rules say that a Contest of two opposing living beings (in this case, a deer vs player) should only use a player's raw CD without any Fortitude or skill bonuses. Does that mean the Hunting skill (and others like it) wouldn't be used in trying to kill a deer but only - say - in tracking/locating it? What about if a player wanted a Sharpshooter or Unarmed Combat skill (they're playing a military character)? If they can't use those skills in combat, would any combat-type skills be pointless to the system?
