Video game from your childhood?

A video game from my childhood would be World of Warcraft. I used to go to an internet cafe with my brother and we would play WoW. Or at least, I would try. So now I'm really hyped for the upcoming World of Warcraft Classic that Blizzard teased at recently.
There are also a few ps1 games that I vaguely remember but nothing stands out as much as WoW for me.
