You should give Blood Omen another shot, It's a very good game especially later on. Quite difficult at times though. But you get some of the most awesome abilities. Not to mention it's the foundation for the entire rest of the series.

I do recommend the PC version over the Playstation version, the PS version has hellacious load times on it while the PC version has virtually none. I own legit copies of both versions and the PC version is heaven.
