In early editions of Shadowrun, telescopic vision enhancements reduced all ranges by one category per enhancement rank. There were only four categories, so for a person with three ranks of enhancement, all shots were considered point-blank range. Note that that isn't the same as "Reduce range penalty by one rank", it actually carried the point-blank damage bonuses (inherent in the attack roll in that system), and effectively extended the maximum range of the weapon.
Stand on a rooftop in the barrens of Seattle, with a clear view of the eastern horizon (no buildings in the way) and pick off a target in New York City at no range penalty to either spot or to hit.
As the editions advanced, rules got more strange, not less.
A Shaman could summon and control one Spirit per Charisma point he had, or one, whichever was less. The rules didn't say that in so many words, but the Charisma limit was down in black and white, and the other half occurred after they restricted Spirits to their domain, and said you could only have one Spirit of each type at a time. So a City Spirit could be with you in the city, a Forest Spirit in the forest, etc.
The way around that "stupidest rule I ever heard of" was to summon your Spirits, then send them off on away missions. "Remote service" used up all the services the Spirit owed you, so once they left your presence they no longer counted as "in your control", and you could summon another right away.
Also, summoning Spirits caused drain. It did stun damage, unless the Spirit was more dice than your Charisma score. Then it did actual physical damage, and could in fact kill you.
The "stupidest rule I ever heard of" part was that you could heal physical damage with a spell in a matter of moments, while Stun could only be healed naturally, over time. Hurs of time. So a Shaman with any brains always called up the biggest Spirit they could manage without killing themselves. My Coyote Shaman always had the spirit world's version of The Incredible Hulk with him, wherever he went.
We used to say that you couldn't rules-rape that system because rape requires an unwilling victim.
