High Life: Videogame concept idea

[Speedo Cola]

After e3 today, I have thought up a decent game idea (not the best lol) that would probably be fun. Here it is:

Setting: Pre/During/ and After the time of WW1

Background:
Mr. Adam Topo, an American foreigner, is at the forefront of French business, as with the rest of the world. However, he's quite a deceiving businessman. He rips off millions of customers, yet they keep buying. No one can ever get in the market either, because he'll have them assassinated, and pay off the police. He gets away with so much evil in the comfort of his American mansion. He's kicked out his family. Abused his workers. Even killed off his own mother because she showed up on Christmas, when he was "busy."

Meet Alexander Bonnaire. A hard-working family man, Alexander despises Topo. Alex lost his best friend to an infection contracted from drinking a beverage from Topo's company, and Topo had his best friend's brother assassinated because he was going to go to court about it. Living in France, Alex is called to war. His life will soon change.

Cutscene after intro:
You play as Alex. You feel invincible in the war. Nothing can kill you - at least you think. You stumble upon an old artifact one day, not knowing what is really hidden inside of it. Suddenly, you get bold, and decide to charge the Germans. Oops. You die instantly, and have at least 100 bullet holes.
However, you suddenly wake up in the Hospital, in America:

"Mr. Topo, about time you woke up! We thought you would never come back after the, ehh... overdose. We told the media you were shot by a robber while attempting to defend your home. They believed it, so no worries. It's a good thing you made it. You had several family members claiming your business, and I know the company would just crumble then... oh, and I've arranged a cab for your journey home..."

Alex was confused. Why was he in the body of the person he absolutely despised? And where was the soul of Mr. Topo? 

Gameplay:
As Mr. Topo, you decide your story. Will you change, and become a nice, charitable person? Or, will you become even more evil, and assassinate whole families? You can invest in companys, develop a new product, change ingredients or parts in a product, get rid of a product, assassinate anyone, hire anyone, fire anyone, donate, or even splurge on yourself. You can win your old French family back, or start a new one. Continue using drugs (yes, it simulates all kinds of drugs), or become sober. You can buy a new mansion, live in the streets, kill random people, bribe police, bribe juries, admit wrong, get locked up, all sorts of stuff. 

As you become a nicer guy, you risk: 
Assassination from other businessmen, and family members
Getting robbed

However, you may also receive:
More money cause you're a trusted businessman
More trust
Easier deals
Less likely chance of getting locked up
And a lot more

As you become even more sadistic, you risk:
Getting exposed
Getting killed as part of revenge
Going broke
More

However, enemies fear you more, you're less likely to be assassinated, and money could be easier.

There are many more results than the ones above.

Also, the artifact will play a big part in the story. As you level up, you can use it to freeze time, look into the future, and more abilities. Also, at the end, you can use it to go back to your old french life if you want, and play a few war missions. 

Every person defines their story. You may end up broke. You might get rich again. You may end up richer than before. You can keep playing, and get further on with life. If you die, you can go back to the last checkpoint, or restart the whole story. Whatever you prefer.

Just some advice: put gameplay first. If you must, include a blurb about the story if it'll make the gameplay make more sense. But only have the breakdown of the story after the gameplay. That goes for the breakdown of the gameplay too. So you might want to consider:

 

Story idea / overall thematics

Gameplay structures, genres, and cameras

Gameplay breakdown

Story breakdown

 

So, for example:

 

You're in WWII and have beaten the Nazis but they come back as zombies

1st-Person, FPS, endless survival horror

yada yada

115 935 yada yada

 

You need to decide on your gameplay some more. What you have for gameplay looks more like branching stories. What will the player being doing exactly?
