RPG

Hi y'all, I was interested in running a Buffy style Urban Fantasy game, I had a look through some of the more obvious and popular choices like the Buffy RPG and the World of Darkness and Curseborne options, as well as the Powered by the Apocalypse games like Monster of the Week.

My problem with those tho is that they're all rules lite, and I prefer a bit more structure to my games, can anyone offer any recommendations? cos otherwise I was thinking about homebrewing over the Dark Heresy rules.

Thanks in advance!
