Insurgency is a bit like that too...
Personally, I like it... I don't
dislike the less realistic shooters like Battlefield or whatnot, but the amount of shots you have to land on someone to take them out in a lot of other games just gives those damned kids with their damned reflexes too much opportunity to outplay me
In Insurgency everyone pretty much goes down in one hit, so it's much less about "outplaying" your opponent in a 1 on 1 gunfight, and more about tactics and positioning. The flipside I guess is that you go down very fast as well and sometimes it will feel like it was out of nowhere, but that I think comes down to learning the maps a bit and understanding why you were positioning yourself stupidly
