ehhh not quite
I agree with the people talking about balance issues. I don't think hit points or powers are dissimilar by any means, but the "realistic" points are inconsistent. You get set on fire, it doesn't go out and you die quickly, that's realistic; your enemy takes 20 assault rifle round and barely loses 1/3 of his hit points, that's grossly unrealistic. If you're going to make certain things insta-kills because that's what would happen in real life, then even the pistol should be a one-hit kill.
