And if Rockstar did that the game probably would never make it to shelves. Especially in other countries than america.. because america lets go of a lot. And i agree, it's not a horror game. I'd rather see time spent on Ragdoll* and Nature.* When someone gets hit by a car, i don't want to see guts, i want to see their bodies flipping and twirling in the area like real life. I'm not into the pre-animated bodies being thrown everywhere.
Take a look at Saint's Row, they have ragdoll and I'm 70% sure that Rockstar has already implemented ragdoll code.
