This is actually one of the main reasons I picked up d20 Modern. It's not so much that I hate the Storyteller system as I hate the expectations of the players when they're using it. They bring all of the OOC WoD knowledge to the table. It's my hope that by running a Hunter game using d20 Modern and mixing up the selection of supernatural threats, I can keep them guessing and foster a more paranoid, uncertain atmosphere.
Now, as to go to go about it, I haven't given it a great deal of thought yet. The Creeds, Virtues, Conviction, and Edges need to make their way in somehow. Conviction and Virtues look like they'll be the hard part, as they an aspect that shouldn't just be glossed over; they're essentially a degeneration mechanic. If any one gets too high, the character is no longer considered playable.
Anyway, just thinking out loud. I need to put some real thought into this.
