I remember playing this game in my youth, so sometimes in the late 90s or possibly early 2000s. The game had both Sci-fi and fantasy mixed up together. I think that the main character was called tom or Tommy or possibly Joe. (not quite sure there)
The setting was on a different planet and I remember that there were some aliens you could recruit in your party.
Cant remember the game or if it had a book attached to it. My kid is about the age I was back then and I would love for him to try this marvel of the last century for himself coz it seems that the saying "apple doesn't fall far from the tree" is true in this case. We like the same games and we both have an uncanny way of finding games we like.
EDIT: As Richard kindly pointed out I forgot something important. The game was for PC and it was a RPG game.
So the question is what is the name of the game? and Does the game have a "world setting" like Dragon lance, Forgotten realm or is it a standalone?
