I think at least OoT and TP have sold more than TLOU.
I also think that if you walked to the average person on the street, they would know and recognize Zelda more than they would know and recognize TLOU.
Your underplaying TLOU a little bit. It's very well known to the average person now, especially considering that zombie or anything resembling zombie apocalypse is pretty popular these days. It's kind of one of those very popular PlayStation games that actually is popular in popular culture.
