This is a personal favorite of mine and will always warrant a spot on any, “What the hell is going on here?” list. Lisa is the story of a post-apocalyptic world that is entirely populated by men. One man finds a baby in the middle of nowhere and discovers that he is a she. This should be impossible! While that all sounds fairly straightforward, Lisa has a bizarre subplot that can be super confusing. There are many moments within the game that are not fully explained. Like who is Lisa? Guess you'll just have to play to find out.
