Demo's Souls -> Your parents run a very famous game company, and you recently joined that company. One day, some haters assaulted your company. They killed everyone, but you survived because your company's fanboy squad sacrificed their lives to save you. Now all you have left is a demo of your company's latest project. As the last surviving member, your duty is to continue the project, to return your company to its former glory, and to honor the souls of your dead employees and fanboys.
Left 4 Dad -> A game about finding your lost dad, or new dad if you are ok with that.
Game summary: In this economy, even the dead can't get a free ride to heaven. Play as a male or a female ghost character and start turning tricks on the street to buy your way to heaven before the devil claims your soul.
- --- God, I have to work both sides of the street to pay that off!!
Please note that I say that in all seriousness; I've never played the original, and I rented the NiGHTS game for the Wii a few years ago and never really got into it, though I very much would like to try the game again.
So... what have I done? --- "I've seen tons of people who love the old Pokemon and burn the new ones on the stake, but I've actually never seen the opposite =/" - JoJoX200
