I've found recently a few official freebie starter kits to various old World of Darkness settings available here for example. While the general settings are the same to the one I know from (which i believe is 2nd edition), this ones have completely different, simplified mechanic based on D6 instead of D10 and greatly simplifying some rules to the point of absurd(i.e. if Arhoun Get gets on start +2 dices in attack!). What version is this?
All but "Geist the Sin-Eaters" belong to the classic World of Darkness.
I think that was in the revised era when White Wolf launched those starter kits. They are not a previous version of the rules. They are small games with very simple rules and the same setting of the core books.
The aim was to attract people to the game universes with a simpler set of rules and a summarized explanation of the setting. Expecting that, if the players like the game, they would jump to the serious full core games.
