ok not a full fledged story but some basic concept for horror survival games

what i believe is horror does not come from digusting and terrifying looking creatures...makes you wanna throw up. it shuold all be a bout experince...like i have only one way to proceed ahead and know that there is something there but i'm too freaked out to go there. so let me cut the crap and com to the story!

there is a man james who's wife and 2 kids have been murdered...but he keeps finding them moving in and around the house(starting of the game... playable area) ...hiding in corners that too in a messy state. one day he regains conciousness in his plastics factory where they were murdered(it's going to be huge coz it's the main area). and hears a voice "daddy it hurts"...but does not follow it instead he tries to run away but finds it difficult to escape...he goes to some offices and rooms where he finds blood written note like "what have u done james who would u blame"..."it's time toavenge us daddy mommy is very angry" and etc. he often encounters his wife or children coming close from the back and he closes his eyes in fear and they disappear. he see them running into room and saying "come on in honey(or daddy) do what you need to". there will be all kind of scary stuff as per the abaove para. finally he'll find a shadow of a man and will chase him...will pick up a medium plastic cutter and wich reach to him and as it seems like he is stabbing that man but instead he stabs himself. now in the ending cut scene it's shown that ...the man was his manager ...he grabs james..and says (james' family standing beside as he spaeks) "james oh god james! shit what happened i just came here to check saw someone on the camera...u should've called me james...what happened james"(his voice fading)...and james family speaking "well do you remeber now daddy do you" and "quite fair hunh james come finaly we can live in peace"
ending story- jame had an affair with some girl sasha and whom he wanted to marry. he dicides to kill all his family (her wife not ready to give divorce)in the factory. he managed to kill his children(ruthlessly) but the wife escapes and tries to run...james and sasha both follow her from different directions...james find his wife and struggles to kill her also sasha reaches there...james stabs his wife and sasha in attempt to knock james' wife she accidently hits james on his head..causing his memory loss for the accident and sasha!
