If you like action/rpg, then go try out Morrowind, The Elder Scrolls III. Think of that game as a true fantasty GTA. If you thought Bloodlines was wide open, Morrowind will blow your mind. For example– in Morrowind you can go anywhere, at any time. You don’t need to unlock the area like in Bloodlines. You just go out of the city, and explore any part of the 10 square mile island. (well that’s a lie, there’s one part you can’t explore until the end.) The class system is even more versatile than Bloodlines as well– you take 10 skills out of 27, and that’s your class– or take a test like in Bloodlines, or choose from a pregenerated class. You can be a fighter, thief, mage, or anything in between. Add the 2 expansions, which add even huger areas to the game, and you have an immense amount of stuff to explore, all in hybrid 1st/3rd person play style. Also, unlike Bloodlines, Morrowind has a great modding tool included, so you have dozens and dozens of mods to choose from when you play.

Nocturne was a great game, although the controls where horrible. It was mostly third person, but if you switched on your Night Vision, you were in First Person mode for limited time. Its prety creepy fighting zombies in a small town in texas, with night vision on!! Plus the game has Zombies, Vampires, Werewolfs, Gangster Zombies and more Zombies. The plot though is pretty linear and NPC interaction is limited to whatever involves the plot.

Deus Ex and Deus Ex 2 to a lesser extent are very similar to Bloodlines, though more heavy on action than rp.
Its a few years old and is set in a cyberpunk world instead of a gothicpunk setting, but you build your character as the game progresses, choosing skills and nanotech bio upgrades with xp, its first person and you can optimize your character for different styles of play (stealthy, unarmed, shooty shooty)
Its definitly more action than RPG if thats your bag
