Vampire the Requium 1at Edition (Mature not Adult)
I would recommend checking out 2nd if you get a chance. Really, all the 2nd ed CofD games are HUGE improvements over the originals mechanically speaking, arguably Vampire got the best fixes too.
The only thing I can imagine you might not like at first glance are conditions and tilts, but actually it's an improvement once you wrap your head around the difference.
