Clan Quest Mod is an add-on for Vampire the Masquerade: Bloodlines that not only adds many new quests along with a myriad of other new features, but also integrates several other mods for the game, including the Arsenal Mod, the Camarilla Edition Mod, Companion Mod, and more!

Awesome stuff. We need more people like you for this game :)
Maybe you could consider giving some small reward for each achievement? Not necessarily XP, but something like +1 point to aggravated damage defence or increasing health regeneration speed. It would encourage to play to the full a lot stronger. Alpha Protocol did it quite well.
If possible that is a really fun idea
