without a doubt, pokemon haha ​​when I was a kid the first one (GameBoy) couldn't save the game, so you had to take it to the end as much as you could before the batteries ran out (2 AA batteries were used) or before your mother would send you to sleep or demand some task from you that would make you stop playing. hahaha in a single day at that time I played up to 10 hours or more, it was crazy. I have always enjoyed games so during my adolescence I was also able to enjoy a game console, and without thinking too much I could say that the game to which I dedicated the most hours, both in one day and in general, was (Gran Turismo) What a special day it was those earning licenses and completing circuits.
