Whether to start is the ICO?

Hi I want to run ico for a computer game, tell me is it a good idea? You also provide a small description of the game

Day of Atonement in the development of the computer game genre Open Action > Stealth > Action Horror > Survival Horror dedicated to survival during the end of the world, the Development of the game deals with a young independent Studio BSG. The main features of the upcoming game developers called open-changing world, a developed system of production of useful things and weapons, the influence of weather conditions on the character.
The game takes place post-Soviet Republics where the onset of darkness, the Apocalypse, where all sinners caught between earth and hell become shadows of purgatory escaped the werewolves in order to punish the survivors. People only need one, to run and to work together to survive even a night.
A new game begins with choosing a character (each with their own abilities, for example the COP handy with a weapon, the priest is a good fight with evil spirits, the engineer can fix and build almost everything, etc.)
The player is not constrained in the choice of means or methods of survival. You can pillage and loot (the important thing is not to overdo it and not become a sinner, because then all the forces of evil will seek to get hold of your soul) and you can create a group and build a fortress to repel the whole "evil spirits" and to survive, which by the way is quite difficult, as all "evil" has a unique intelligence, which for sure will not get bored.
Gradually, the game difficulty increases the activity of the shadow increases, the part of the players becomes a bloodthirsty werewolves electricity and water supply disabled items and weapons break down, runs out of fuel, so the player needs is moving day to have time to restock or repair is necessary for survival stuff and weapons to night, after night there comes the real hell on earth shadows become tangible and begin hunting. The player can be saved to the previously created refuge, which must be light, because the shadows live only in the dark, but we shouldn't rejoice if you're holed up in their shelter and believe that you will survive, mistaken, there are still werewolves and they are not so much afraid of the light as shadows, and likely part of the werewolf is infected by the bite of players who need to kill and eat the flesh with the blood for survival. To kill someone is very difficult, because by nightfall, he ceases to be human, reincarnated into a wild and strong creature.
In the game as there is a currency which can be used to buy and sell different useful things and weapons. With every new updates will be new, unexplored locations and due to the open world, unique game atmosphere, and a unique intelligence all kinds of "evil", and different individual possibilities of each character, the ability to side with evil and become a werewolf when infected through the bite of the huge options of creating use of for the survival of useful things and weapons, will keep you in this game for a long time.
And this is only a small part of the possibilities of this game.
