Ooh. Chaosium. I used to be a huge fan, still am, of 6th edition Call of Cthulhu. I still have some of the books somewhere. I love the percentile system for teaching new players, it's so much easier even if the game is hella lethal. I haven't seen the system from DA.

Feel free to friend me on Plurk at BrimstoneMuse if you like, always glad to have another tabletop veteran around!
