I ran a game! And it didn't suck!

( Preface )

Best out of character line of the night:

"Can we catch him?"

"He's a vampire Watcher with his head on fire. No. No force on this earth can catch him."

But they did. I'm so proud of them. My little Slayer took down a very dangerous undead rogue Watcher. And in true Buffy style, she did it because she wouldn't play by his rules and kept a ridiculous number of helpful friends around her at all times.

( I really liked writing this villain. )

Between all the members of my little group (I'd list them, but it sounds too silly), they had him running like a bitch, and he still couldn't get away.

A ridiculous number of helpful friends

Warning, game geekery.

So, when I wanted to explain why my last villain got trounced, I realized even a partial listing of the reasons would sound so cheesy it hurts. As a GM, I'm allergic to cheese. I hate it. I try like hell to never give anyone toys that don't match the nature of the world or seem too coincidentally convenient.

But I just took a long soul-searching look at the make-up of my game's cast, and decided that they're way overpowered.

( A listing of characters and their toys )

So. They have a very powerful, nigh-omniscient Big Bad to face (the Djinn roughly outlined in the sourcebook), and they can't fight it particularly effectively with these toys, but it's making anything smaller a romp.

Do I cut down their power level? Accept that they're attached to their toys and up the other monsters? Or do I let them romp through the smaller villains because it obviously makes them happy to do so?

And am I missing any choices? How do people handle this situation, and how do I turn my heart to stone to stop giving them bonuses that "seem reasonable at the time"?

I throw myself on the altar of Good Plot and Fun Game. What must I do?
