Capstone Ideas Left on the Cutting Room Floor

During the past two years, I've been trying to come up with ideas for my capstone. There were some really good ones that had a great story, but I couldn't really figure out where to take it from there.

The 1st Idea:
This idea came from when I was in my Four Horsemen phase. The main character was a kid who thought he was just an ordinary high school student, everything was going great for him until one night he, his girlfriend were attacked by things that didn't seem human. Turns out his family holds a dark secret that his mother tried to keep him from, the men in his family ran hell and they wanted him to take the mantle of the Grim Reaper. He reluctantly agrees to do it to save the souls of his friend and girlfriend. As he takes jobs from them, he finds out that they were never going to bring them back and he was just being groomed to have his heart and soul taken from him s he could be a loyal servant to the family. So he decides to take the fight to him one by one and steal their power from them. At the end of the game, his mind has become so warped by what has happened and what he has become, an angelic figure has come down to try and stop him from killing his father and taking the crown as the new king of hell. So the player would have a choice to kill their father or to let the figure reset everything back to it was before the faithful night, him and his friend, and girlfriend would be protected from what happens.

The 2nd Idea:
This was game idea I almost took the whole way. The kid is coming home from school with his friends when his hated rival shows up. The rival starts something and they end up fighting, the rival pushes him into the street where he is hit by a car. As he is fading in and out of consciousness, he wakes up to being in another world that is made up of the heroes and villains of the games he plays, but everybody he knows has taken the appearance of his real life friends, family, and other people that he has come in contact with. Everything that happens in his mind affects his body in real life. So the player would have to beat the game to get the main character to wake up. This game was going to be a homage and parody of other arcade games from the 80s and 90s.

The 3rd Idea:
This is the idea that I am currently fleshing out for my capstone. This is going to be a level to a side scrolling game that I want to make. The whole game will encompass ideas and philosophies from past games and current games. The level I am doing is going to be a stealth, rogue like section where you have to sneak around and collect jewels and treasures in the haunted Egyptian temple. When you collect and accidentally open up Pandora's Box, this will be the jumping off point for the game and add a supernatural element when King "Tuttin"hamen will wake from his slumber and try to bring back his kingdom and rule the world, by assembling the "8 Evils of the World", which are the "8 Wonders of the World".
