I am not ashamed of this, but all things considered I vastly prefer Charmed to Buffy. I don't even consider myself a Buffy fan to be honest, more of a Willow & Tara fan. But I am an unapologetic Charmed fan.
There is the whole witch thing to be sure. And the Charmed Ones are rather easy on the eyes. But I think my friend and former TV writer Robert Black said it best, Charmed never forgot who their audience was and never forgot they were a TV show.

I am at a really good place in my gaming life. I get to game all the time now with various groups. I get to talk to the people that make this hobby happen and they are really cool. And I get to write the stuff I like.
But I'd kill to be able to write a Charmed RPG.
While I know the demographics of the show and your average gamer are not exactly the same, I think with the amount of "modern supernatural" fiction being published today that a Charmed game would be fantastic. Buffy sold well, Dresden Files is doing nicely. Granted those are properties with significant geek/gamer buy-in and at the time of their games the properties are still active.
I would like to point out that with all the stuff I have written about witches and magic in the things I have published that this game would be a natural for me. ;)
The world of Charmed is richer and it is a drama about sisters that happen to be witches and living in a supernatural world. Not one about witches that happen to be sisters. The differences sound subtle but have huge potential differences on how a story can be told. Charmed featured, not just witches and demons (the typical fare in my book) but all sorts of other races, creatures and groups with agendas of their own; and just because two groups were working for the same side they didn't always get along. For example the Charmed Ones and the Elders or even the Valkyries.
I think there are better stories one can tell in the Charmed universe, actually I know so. One of the premises of Season of the Witch was to take two Buffy characters and put them into a more Charmed like universe and tell a story. It worked. It worked really well in fact.
Of course my system of choice for this would be Unisystem, but I can also see doing it in something like Mutants & Masterminds or even Cortex.. Maybe I need to chase down the company that owns the game rights (I know, or rather knew, who they are) and see if they want to hire me cheap. If Eden were to do it and publish it I'd even consider doing it for free.
There are a couple of versions of Charmed on the web.
Andrew Peregrine, author of Victoriana 2nd ed and Hellcats and Hockeysticks did one way back when. You can still find it here, http://www.peregrine.madasafish.com/charmedrpg/.
Jeff Slick also did one years ago, but all his copies seem to be gone. I did find thins one though, http://www.scribd.com/doc/44502892/Charmed-RPG-Netbook.
I like both, but there are things I'd do different in each one.
At the end of the day though I think a Charmed RPG may never be. More is the pity too. I think I could really rock on writing it.
