Human Low Point Windows game

I would like to create a game where body damage is really realistic. For that I run a fundraising campaign because I need hardware and developer help. I want a game where when you cross a player with your spear, his skin tears, his bones break, his organs come out. Where when you jump too high, your legs break and hold only by the skin. A realistic game, requires a game engine provided for this purpose. For that i need your help. Thx to read me, a crazy french boy <3 You can help me to do it with Paypal donation, all donors will have access to the games, provided that their donation exceeds 10 €.
