Buy it on GOG, I believe the Steam version of Bloodlines doesn’t even launch. GOG version comes bundled with the “basic” version of the Unofficial Patch which - as far as I know - is literally required to be able to finish the game. GOG also has a one-click installer for the Plus Patch with more restored content as of like a month or two ago, if you’re into that. I personally recommend playing non-Malkavian Basic Patch for a first experience and doing Malkavian with the Plus Patch for a second playthrough.

The game is absolutely worth it, it’s a cult classic for a reason. The combat sucks so be prepared for that and the second half of the game is extremely rushed as the developers were forced to shove it out the door but even having said that it’s a great experience for what it is.
