Bloodlines is a great role playing game that suffers from a few overlookable problems.
Depending on what class you pick, other vampires will react to you differently, making the conversation threads and play style change per your choice here. You can also customize your style within your class and as you level, although the leveling process can seem slow at times. For instance if you choose to be one type you will be scorned and will have to play the game from the sewers, mostly. If you are one of the upper class vampires you will be able to charm people and will likely be able to walk through many front doors. If you are the crazy vampire, all of your dialogue will be confusing and you will hear voices from the audio.
One of the best parts about the game is how well the world of Los Angeles Vampire world is set up. You'll likely get into the story and the mysterious intrigue of "The Masquerade" more than you expect, especially as an outsider to the game, like myself.
The physics engine was the same one that they used for Half-Life 2, so you can interact with a lot of things. Unfortunately collision detection is not perfect and the weight of everything, including your own character just feel off. If you have a problem with floaty jumps and cinder blocks that weigh the same as pop cans, then you will have issue with this game. Also if you do not like games with dialogue, you will not like this game. Many choices and changes are made within dialogue.
Fortunately the dialogue is one of the strong points. The story is good and the characters are well imagined. It will get tedious to go back and have the same conversation you had half an hour ago if you die, but you can save at any point, so this isn't often a problem.
There are multiple ways to handle any situation, which draws you back and sometimes makes you want to reload and try again. This makes the gameplay fun and will influence where you put your attribute points and may even cause you to start again with a character that more suits you play style.
Guns are useless and missions that involve them are frustrating at best. The physics are too loose and the graphics are not cutting edge anymore. The gameplay style and story depth overcome these issues, however. Just make sure to download all of the official patches. A recommended RPG experience.
