Just to be clear, though...are we talking Roll Templates, or Character Sheet Templates? I ask, because you can get tricky and create a single character sheet that might accommodate all the different things. For example, WoD is basically the same rule set, with some tweaks depending on if it's Vampire, Werewolf, Mage, etc... I'm not sure how different the rules are for each game, but if 90% of the character information is the same, and if all the rolls are handled the same way, then you could create a single character sheet with a "settings" option that show/hide different fields appropriate for the type of character. If you want to see an example, you can look at the Savage Worlds Tabbed character sheet which accommodates several different settings via this method.
