RPG: Diablo II Shooter: Wolfenstein 3D Adventure: King's Quest (Can not remember which part)
Many of you selected Jump'n'Runs as your first Adventure Games. I'm not sure, if this is correct. (Of course you can do what ever you like.) Wikipedia says:
An adventure game is a video game in which the player assumes the role of protagonist in an interactive story driven by exploration and puzzle-solving instead of physical challenge.
But in jump'n'run games i think the focus is on the "hysical challenge". Please correct me if I'm wrong.
Wow, this is a hard one to answer. It's been so long...
RPG: I'm gonna say Morrowind. That's my best guess. Shooter: Maybe one of the Delta Force games, maybe Serious Sam. Again, not sure. Adventure: This was Super Mario World, Spyro, or Crash Bandicoot. Yet once again, I'm not sure.
