What do you think about this story for a video game?

Hi all. I am a computer science student doing a higher year project. I have decided to do mine on storytelling and emotional attachment to video games (i am also minoring in psychology).

Basically I am going to make a game about empiricism vs religion.

It will be about the end of the world and god sending harvesters to cultivate the souls of the last humans. The best scientists in the world gather and reverse engineer this technology. The player character is a marine and one of the last best soldiers on earth.You go around harvesting god’s servants until eventually you are the last human left.

There will be a lot of twists and intrigue since your most trusted confidant will betray you and turn out to be a zealot. Eventually you will harvest Jesus’s earthly remains and become part god yourself. So the final showdown is between you and the abrahamic god. There will be a branching storyline where basically god offers to make you his right hand man and revive your dead girlfriend so you can live with her in heaven. Or you can kill god and take his place and rebuild humanity from scratch (which will be the prologue if you choose that path).

What do you guys think? Could this be a story that you would be interested in, that affects you and that you could get emotionally attached to? Thanks!
