In Waldo and its followup, Magic Inc, the introduction of magic didn't eliminate technology, or cause civilization to crumble - it supplemented technology, enabling devices to do things they couldn't do before (like the flying cars, using an antigravity spell). And honestly, I think I'd rather play in a campaign where magic is supplementing and replacing tech, not causing it to fail - there are still going to be those opposing the process, those seeking to accelerate it, and those who just haven't adapted yet to, say, spies who use crystal balls and have to be stopped by antimagic spells. (Just avoid the high levels of pessimism that permeated Shadowrun... :) ) Oh, and occasional surprises as someone combines things that haven't been combined before, like say a Fireball spell imbued in a BB to give you the world's smallest grenade launcher.

Which also reminds me, that was my only issue with oWoD - it was so very pessimistic. Every metastory in the entire line seemed to be bending toward the End Of the World - which was coming Very Soon. I far prefer nWoD's meta, where there's hope for the future even if you're undead - sure, as a Kindred you're living a life of despair preying upon your former loved ones and only ever able to experience shadows of the emotions you once felt, but there might be a possible way out, and if you want to pursue it you've got centuries to work with (as long as you can avoid Final Death).
