lol burn. Gen over gen is always the best way to gauge real success. And profit offcourse.

What about PS1 then? 

What if PS1 had sold 30m and PS2 100m? Would the PS2 have been an even bigger success, then?

Naturally yes, but try to stay away from hypothetical numbers. PS2 outsold PS1 so naturally thats sustainable success.
