I am looking for the 1997 strategy board game "Monster Master" by "O.T.T. Software" also known as "Monster Master: The 13th Chair" or "Monster Master: Die 13. Kammer"
I searched for the game in the Old games archives but they have removed it completely
Game Overview: Monster Master
Genre: 3D Turn-based Strategy / Board Game.
Characters: You chose from a roster of classic horror monsters, including Dracula, Frankenstein's Monster, a Werewolf, and a Mummy.
The Goal: Players moved around a 3D town map trying to "capture" or control buildings. The player who controlled the most of the town (or achieved a certain score) would win.
Building Mechanics: This matches your memory perfectly. Each building had a unique interaction with the monsters:
The Hospital: As you noted, this was a strategic tile. For Dracula, it provided an endless blood supply (acting as a health or power boost). However, if Frankenstein entered it, he would be subjected to a brain surgery (which acted as a handicap or "lobotomy" effect that hindered him).
The Laboratory: Usually a benefit for Frankenstein but could be a hazard for others.
The Graveyard: Often served as a "home base" or spawning point for certain undead characters.
