Just a general game concept

so I'm always having ideas for games and I thought maybe i'd start sharing them if you guys wanted to hear them. some of which I'd love to work on some day. here's a concept I pieced together last night:

video game idea:

a baby is born and spontaneously combusts nuclearly,

the nuclear explosion leads to a wide expanse of changes across the world leading to

a planet of chocolate. you play as donut-boy a chocolite of the newly formed Planetoid-Willy (was earth). 

during your quest you get to choose from 4 factions, your own 

(the chocolate satanists), Dragon-Space-Hitler, The Vietnamese socialist union, and 

the cult of semi-cannibalistic cannibals. you get a different ending depending upon

which faction you've chosen. choosing Dragon-Space-Hitler leads to you conquering the

galaxy and destroying it. choosing the chocolate people will raise satan from hell causing 

your entire world to be lost to hellfire, choosing the cultists you yourself will be eaten by mistake,

and choosing the Vietnamese Socialist Union will lead to a massive economic collapse and the entire galaxy being claimed by the IRS.

the games premise:

you play as donut boy it's a 3d platformer with various differing stages. with a handful of selectable weapons

you've just made your way out to the world and now must choose a life for yourself

and what you want to do with your life, the galaxy is facing the threat of extinction

and it's up to you to coast through life ignoring that fact.

you'd fight different enemies based upon your chosen faction.

what do you guys think?
