Realism Versus is a good game mode because it makes it tougher for the survivors. Anyone who has played L4D2 for a considerable period of time probably realizes the survivors are overpowered. This is why some people play hardcore variants of Versus that reduce health packs, tier 2/3 weapons, and beef up special infected. I've played 250+ hours of L4D2 and in my experience RV makes teamwork more important and special infected more able to inflict damage. It actually makes surviving each stage a challenge.
