This game is my obsession.
Why? Because this game is so me! The dingy clubs, the wandering homeless people, the music, the mood...I'm basically a vampire (^‿^v). But really, if you haven't played this game, look into it! It's not for everyone, and it's a bit dated, but it's a cool experience (especially because it feels like you time-traveled back into the early 2000s zeitgeist).
My favorite clan to play as is Gangrel; Protean is such a cool power. I feel like it's the only discipline in the game that grows alongsideyou. But also frenzy bonuses are so overpowered on a low-humanity character.
The other clans are also cool too, like the Ventrue are awesome for their Dominate dialogue, the Tremere get the cool blood magic, the Nosferatu get fun dialogue and a nice obfuscate and potence combo, the Malkavians get dementation, and the Brujah and Toreador get Celerity.
Funny anecdote: to play this game, you need the community unofficial patch, so when I was installing, I accidentally installed another mod (the Antitribu mod) because I thought it was also needed. So, the first time I played this game, I played as a Tzimisce; it was really fun. I'm also a huge nerd for the mods for the game, like I've played all of them and check Planet Vampire and ModDB for the game! I'm very obsessed, lol. Maybe I'm a Toreador at heart.
