This is probably the world’s perfect analogy of what a stepfather is. I remember the good ol days of Pokemon and I even bought a few games used. Nothing was better than finding out that the dude before you was a world class Pokemon trainer and had tons of high levels. This would be an example of being a step father to a kid that turns out to be a NFL superstar or a rich ass mother fucker.
On the other hand, you could have a previous owner of the game that sucked balls with shitty pokemon and low levels. This would be an example of being a stepfather of a kid who sucks at life and is just a waste of space.
