I think you have the beginning of something. and you get the issue: you wanted to create a too big game in a too small amount of time. If you review the scope to a less impressive games (I mean, you try to create a flight simulator with a story!!!), I think it should be fun to get a story to live with a (or multiple) monster while flying a plane over the ocean. Would be very poetical. Don't you think?
congrats for this idea!
