Generally, to me it's not just a question of realism for realism itself, but also a question of gameplay and aesthetics.
For example in OFP there's stuff that I like as gameplay mechanics - having to avoid getting hit, preferably by avoiding getting seen, having to master the weapon and be able to hit things taking in account ballistics, fighting to first accurate hit, etc.
Then when it comes to aesthetics, I like when I hit someone with a burst and he/she falls down or can't stand or something like that. I see certain beauty in it. I like it even more when he/she doesn't just die, but for example folds up and screams or does something equally interesting.
While I find Warsow, satisfying challenge-wise, I don't find it satisfying aesthetically.
