It depends on your standards for visuals and voice acting in relation to how much you enjoy game mechanics. I would say that the game still holds up fairly well in terms of the incredible gameplay and has not been matched since - however the visuals, plot and voice acting are pretty bad, even for its time (2001). If those downsides bother you too much, then it might not be for you.
But if you haven't played it before, you definitely should. It is in many ways a masterpiece in terms of game mechanics.
