I'm a massive Roleplayer. I'm never sad if a game goes by with out a roll. I just like the feeling of a pool of dice representing all the skill the character has over 1 d20 and a random number to meet or beat that the DM has to come up with. Can't really explain it better, but I'll echo that it'll be easier just to theme and/or freshbuild d20Mod then try and crush all of WoD into d20. That, or use Mutants and Masterminds or GURPS or BESM (d20 variant, if you REALLY want)
