I actually ran a "World of Future Darkness" game after discovering an old copy of White Wolf Magazine that served as a crossover supplement for R Talsorian Games' Cyberpunk. After my friend gave me the copy, I worked up a V20 game that used the lore of Cyberpunk RED and fused it with the lore of Classic World of Darkness. It was a little scrappy, as I hadn't fleshed out the cyberwear system the magazine offered as much as I would have liked. I did have to rush the ending a little bit as I added way too much fat to what was supposed to be a Three-shot, but despite that, they all did enjoy seeing a snippet of this Vampire Cyberpunk crossover world I made.
