No, the problem is that there’s an undeveloped market of people who would like to have futuristic realistic battles.
We are currently in the reign of the platform generation. Fast, accurate, gameplay is what sells. Soon will come the reign of the Minecraft generation, and a different type of games will sell.
Make a game with gameplay similar to futuristic realistic battles and sell it to every gamer below the age of 10 and maybe, 40 years from now, your game will be worth spending money on.
Of course, even then you probably wont enjoy it beyond “well it was interesting to spend a couple of hours on”.
