If you need your fix of uncharted island survival between now and whenever the writers start getting their money, I recommend Aspyr's Virtual Villagers. This game, developed by Last Day of Work and originally published by Big Fish Games (both of which are related to Lost in title, anyway), gives you control over a large number of people as they try to survive on a deserted island. No plane crash here, though. They were fleeing a volcanic eruption, and apparently did so by sailing to a neighboring island. Not sure what they did for a living before they got there, but it apparently wasn't survive, because they've forgotten everything that entails...
