Isn't rule 4 geek the mage first?
It was. But that brings up one of the things I liked especially about the game system. It had some of the finest game balancing I've ever seen before or since, all the way up to and including 4th edition which was the pinnacle in my opinion.
Here's the thing of it - D&D 4e had superb balancing (at the start) but it did it by grinding everything down to working more or less the same way with different flavour. Magic and tech in Shadowrun did play substantially differently but each had its positives and negatives nicely set against each other. Tech, on the whole, was very reliable steady output. Magic could be more powerful but had comparative risk. It had spells but they weren't Vancian magic where you used them up. Instead you decided how hard you wanted to cast them with an eternal temptation to get carried away, and could injure yourself in doing so. The element that I think made Shadowrun balancing possible is a subtle one but I think it was critical. In the Shadowrun system, offence nearly always outpaced defence. Yes, you could sustain some Armour spell or layer yourself up with dermal plating and hard armour but nuyen for nuyen or karma point for karma point, what you mostly found was you could hit harder than you could take. And that was true for both tech and magic. And because you had that underlying truism, it mitigated any imbalances between Magic and Tech because Magic v. Tech was now a less significant axis than Offence v. Defence. You could argue over whether a Manaball or a Frag Grenade were best but in both cases, the key was to get the drop on the enemy and hit them with it first.
I'd often see people claim that magic was over-powered and every time it turned out that the GM was ignoring some rule or consequence. Or that the party was just enabling it like everybody pooling their nuyen to bind some high-force spirit. I mean - don't complain that the mage player is better than your samurai character when you're willingly giving half your earnings from the run to the mage player to enable him to be so!
I found this sort of thinking a problem with many groups where the players veered younger, including non-Shadowrun crime campaigns I ran. Player: "We don't have any money!". Me: "The job paid 10,000 and you spent 8,000 on gear and bribes and other things to complete it."
They just can't get their head around resource management. In my last campaign I actually had the team come out
in debt from completing the mission because they spent more during the mission than it actually paid.
