MiseryMade

I think that if you can make your idea different enough, that you should go ahead and go for it! If you think on it long enough, you're bound to come up with something that is different enough from the game that you'll be able to capture the interest of some readers.

I think that maybe something like "Begin, Fight, Die, Repeat" or "Begin, Die, Repeat" would be a good idea for the story if you don't want to give too much away to people who are potentially going to read your story.

I think that it would be an interesting prospect to see what they went through each time they died. What happened before they came back; if it was the same every time or if each time was something worse, something different? And does it happen every every time they die, or at some point does that stop?
