Parasite Eve.

Heck, it made me want to study biology to understand cells, mitochondria and genetics xD

Different game but same effect:

Deus Ex

Made me want to take up Biotechnology. It basically influenced my choice of degree which has impacted on my entire career progression.

Prior to playing Deus Ex I was going to do Computer Science.
