If you are curious, the game you’ve never heard of is definitely in the realm of “cult classic”.
The Legacy of Kain series is flawed in many ways; its reach exceeds its grasp in every installment, but there is a lot of solid vampire angst in between the places where the budget ran out. When it comes together it’s great IMHO.
Start with Soul Reaver, where you are a vampire who is killed in the opening cinematic, then resurrected as a Double Vampire who eats vampire souls in a dying world while railing against your Inevitable Doomed Destiny. Which, just so you know, is not resolved until Soul Reaver 2. Which IMHO you should play before either of the Kain games if you enjoy Soul Reaver.
These games are goth as fuck. If you do not have an inner goth then it’s probably going to feel like a bunch of pretentious whiny shit. But if you have an inner goth, she will eat this series up. My inner goth is quietly vibrating and squealing at this tiny, vague possibility of more Legacy of Kain.
