I know the developers dont want to borrow ideas from other games, but a really good game to emulate would be Lost in Blue or Lost in Blue 2 for Nintendo DS - you play as one of two people stuck on an island trying to create shelter & gather/prepare food & survive the elements & all sorts of other things which are similar to the VV games like figuring out the mysteries of the island...oh lord now that I've started talking about it, I've GOT to get back to my game!
