Games you remember playing but can't remember the name

[SamChurch]

Another game I used to play on my PC back when desktops were a huge TV-like monitor and a tower. This game is a bit hard to describe. Basically, you were a vampire. You had a character picture that would move in the middle of your...more or less HUD, but I could never figure out a pattern to it. There might've been more to the game than I remember but the whole time all I did was walk up to people in the streets and completely drain them. I was a bit of a prick actually.

2d or 3d?

3D, If it helps any I thought graphically it was a little better than Darkstone
