i really dislike "run and gun" shooters where you just spray enemies down with a seemingly endless supply of bullets. you don't even have to stop and carefully aim, you just fire into the general area of your enemies.
i much prefer having scarce ammo, so you have to make every single bullet count, and you have to carefully place the bullet into an enemy's weak spot (such as the head) to get the most damage out of it.
resident evil 4 and 5 are pretty much the only games with that kind of style that i can think of. is there any other games like that?
