I actually like realism in a game. It's easy to point at an enemy and click buttons until they're dead, it's harder to remember that you need to take care of yourself in a virtual world.
Realism mods are good for the difficulty, not the 'immersion' they pretend to add, real life is hard, you have to remember to not let yourself die sometimes, its nice to be reminded of that in a safe way
I've decided to start tagging my drunk posts as such, just in case I wake up and find out I've said some bullshit, this is a drunk post.
