Where'd That 6th Toe Come From?
That the point, you don't know why he left. You are removed from the only place you have ever known, your father is the only person you know, and who hold answers. Most people will seek that anchor. In comparison in FO2 there is FAR less compelling reason to care about your backward tribal community, much less so after seeing the big world and all it holds.
I don't find too compelling knowing why he left either. The important thing here is the following: he knew the deal with the Vault, and chose to leave me. Not worth it, he can be deathclaw food for all I care. I am more likely to care for Amata, as stupid as the character was, at least she shows any interest in my survival. Same for all I can guess about the tribe.
And that is fine, I am not saying that it was great, only that fallout 2 provided far less reasons to care about the mission.(this was used to contrast the OP populism) Btw, I bet that the reason why so many of us remember FO2 fondly is because it used the teenage fantasy trope: orphan, trained from birth you are the chosen one, the villages only hope. Sent on a quest for the holy grail to save your people... and the eventually the world! - you even get to fight the black knight
