This tells us nothing about the game other than “it’s a shooter with graphics”. Which is pretty much any FPS. Given how varied an FPS can be, we still know nothing about your idea. What kind of game mechanics are you going to have? Are you going to have any features that haven’t been seen in an FPS before (or rarely seen?), something to set your game apart. What will the combat be like. What will the weapons be like? Will the player have powers an abilities, or will it be a more simple run and gun a la Serious Sam?
Not saying you need to tell us all of this (in fact some of it is probably better kept to yourself!), but these are the sort of things you’ll want to think about and flesh out. You won’t sell a game for $50 on just “FPS with advanced graphics”. Not without a big publisher backing you imo.
I’m a bit confused by this. If someone isn’t interested in a game, why would they play it?
