I have to agree with Tigranes. I did play VTM by recomendation of a friend who lent me his copy and I couldn't put up with it for 10 minutes without going out on the internet in search for a patch. I have yet to run into any real bugs that a few people have reported in, except the obvious jerky mouse controls of the camera in a few levels, which can break the fun for a few seconds before I continue on. But it has as Tigranes stated a very smooth launch as far a RPGs go.
But Obsidian have really made a fantastic game and it is just a shame that major game reviewers are giving this such a poor score as a lot of people will listen to those review and walk right on by this game without a second thought and not make up their own mind or even worse they'll pirate it, which won't give Obsidian and Sega much encouragement for a sequal.
